BACKGROUND OF THE INVENTION

It has long been appreciated that chromatin-associated proteins and epigenetic factors play central roles in gene regulation. Mis-regulation of chromatin structure and post-translational modification of histones (PTMs) is linked to cancer and other epigenetic diseases. The field of epigenomics has been transformed by chromatin immunoprecipitation approaches that provide for the localization of a defined protein or post-translationally modified protein to specific chromosomal sites. However, the hierarchy of chromatin-templated events orchestrating the formation and inheritance of different epigenetic states remains poorly understood at a molecular level; there are no current methodologies that allow for determination of all proteins present at a defined, small region of chromatin. Chromatin immunoprecipitation (ChIP) assays have allowed better understanding of genome-wide distribution of proteins and histone modifications within a genome at the nucleosome level. However, ChIP assays are largely confined to examining singular histone PTMs or proteins rather than simultaneous profiling of multiple targets, the inability to determine the co-occupancy of particular histone PTMs, and that ChIP is reliant on the previous identification of the molecular target. Other chromatin immunoprecipitation methodologies do not provide a mechanism for determining the specificity of protein interactions, or do not enrich for a small integrated genomic locus and cannot detect protein contamination in purified material. Therefore, there is a need for methods that allow for determination of all proteins and protein posttranslational modifications specifically associated at a defined, small region of chromatin.

SUMMARY OF THE INVENTION

In an aspect, the present invention encompasses a method of identifying proteins, including proteins comprising posttranslational modifications, specifically associated with a target chromatin in a cell. The method comprises: (a) providing a first cell sample comprising nucleic acid binding proteins and the target chromatin and a tag, wherein the target chromatin is tagged by contacting the target chromatin with a tag capable of specifically recognizing and binding one or more portions of the target chromatin and wherein the tag comprises an affinity handle, and a second cell sample comprising nucleic acid binding proteins and the target chromatin, wherein the target chromatin is not tagged by contacting the target chromatin with a non-functional tag that is not capable of specifically recognizing and binding one or more portions of the target chromatin and wherein the non-functional tag comprises an affinity handle; (b) isolating the affinity handle from each cell sample in (a) wherein affinity handle isolated from the first cell sample consists of affinity handle bound to tagged target chromatin bound to specifically associated nucleic acid binding proteins and affinity handle bound to non-specifically associated nucleic acid binding proteins and affinity handle isolated from the second cell sample consists of affinity handle bound to non-specifically associated nucleic acid binding proteins, wherein isolating the affinity handle enriches for the tagged target chromatin; (c) identifying bound proteins from (b); and (d) determining the amount of each bound protein in each cell sample from (b), wherein bound proteins that are enriched in the first cell sample as compared to the second cell sample are specifically associated with the tagged chromatin in the first cell sample.

BRIEF DESCRIPTION OF THE FIGURES

The application file contains at least one drawing executed in color. Copies of this patent application publication with color drawing(s) will be provided by the Office upon request and payment of the necessary fee.

FIG. 1A and FIG. 1B depict the chromatin affinity purification with mass spectrometry method. (FIG. 1A) The chromatin affinity purification with mass spectrometry (ChAP-MS) approach provides for the specific enrichment of a given chromosome section and identification of specifically associated proteins and post-translational modifications. A LexA DNA affinity handle was engineered just upstream of the GAL1 start codon in S. cerevisiae. Strains containing the LexA DNA binding site and a plasmid expressing LexA-PrA protein affinity handle were cultured in glucose or galactose to provide transcriptional repression or activation, respectively, and subjected to in vivo chemical crosslinking to trap protein interactions. Following shearing of the chromatin to ˜1,000 bp, LexA-PrA was affinity purified on IgG-coated Dynabeads and coenriched proteins/post-translational modifications were identified by high-resolution mass spectrometry. (FIG. 1B) To control for nonspecifically enriched proteins, a strain lacking the LexA DNA binding site, but containing the LexA-PrA plasmid, was cultured isotopically heavy (¹³C₆ ¹⁵N₂-lysine) in glucose or galactose and mixed equally with the corresponding isotopically light culture containing the LexA DNA binding site prior to cell lysis. Following affinity purification (AP) and mass spectrometric analysis, nonspecifically enriched proteins were identified as a 1:1 ratio of light to heavy lysine-containing peptides, while proteins specifically enriched with the chromosome section were identified with a higher level of isotopically light lysine-containing peptides.

FIG. 2A and FIG. 2B depict a plot, a Western blot image and a plot showing DNA affinity handle for purification of a specific chromosome section. (FIG. 2A) S. cerevisiae strain LEXA::GAL1 pLexA-PrA was created by insertion of a LEXA DNA binding site upstream of the GAL1 start codon via homologous recombination. The pLexA-PrA plasmid was introduced into this strain and the constitutive expression of the LexA-PrA fusion protein was confirmed by western blotting for PrA. (FIG. 2B) Introduction of the LEXA DNA binding site does not impede GAL1 transcription. cDNA from wild-type or LEXA::GAL1 pLexA-PrA strains grown in glucose or galactose was used as a template for real time PCR analysis of GAL1 versus ACT1 gene transcription. Error bars are the SE of triplicate analyses.

FIG. 3A, FIG. 3B and FIG. 3C depict plots and a diagram showing efficiency of GAL1 chromatin purification. (FIG. 3A) The effect of buffer stringency on purification of LexA-PrA with associated chromatin was evaluated with ChIP. Strain LEXA::GAL1 pLexA-PrA was subjected to ChIP using the following buffer with the reagents indicated on the graph: 20 mM HEPES (pH 7.4), 0.1% Tween 20, and 2 mM MgCl₂. Enrichment of GAL1 DNA relative to ACT1 DNA was monitored by real-time PCR. (FIG. 3B) ChIP was used to measure the specificity of enrichment of LexA-PrA bound chromatin. Enrichment was monitored by real-time PCR with primer sets at the indicated chromosomal locations. (FIG. 3C) GAL1 chromatin is enriched in both glucose and galactose growth conditions. The relative efficiency of GAL1 enrichment was monitored by real-time PCR with primers targeted to the “0” position in panel (FIG. 3B) and to ACT1. The SE is indicated.

FIG. 4A, FIG. 4B, FIG. 4C and FIG. 4D depict an image of an SDS-PAGE gel and mass spectra showing ChAP-MS analysis of GAL1 chromatin. (FIG. 4A) Enrichment of GAL1 chromatin under transcriptionally repressive glucose and active galactose growth conditions. Strain LEXA::GAL1 pLexA-PrA was grown in either glucose or galactose and subjected to affinity purification of GAL1 chromatin via LexA-PrA as detailed in FIG. 1. Addition of an equivalent amount of isotopically heavy (¹³C₆ ¹⁵N₂-lysine) cells lacking the LexA DNA binding site provided for the identification of proteins specifically enriched with GAL1 chromatin. Proteins coenriching with LexA-PrA were resolved by SDS-PAGE and visualized by Coomassie-staining. Each gel lane was sliced into 2 mm sections. Gel slices were treated with trypsin and resulting peptides were analyzed by high-resolution mass spectrometry. (FIG. 4B, FIG. 4C, FIG. 4D) Representative high-resolution mass spectra from proteins and histone post-translational modifications identified from the purification of transcriptionally active GAL1 chromatin.

FIG. 5 depicts a plot showing proteins and histone post-translational modifications enriched with GAL1 chromatin. Proteins and histone post-translational modifications identified from the ChAP-MS analysis of GAL1 chromatin in the transcriptionally active galactose and repressive glucose growth conditions are listed in accordance to their percent isotopically light. Proteins or post-translational modifications were considered specifically enriched with GAL1 chromatin if the percent isotopically light was 2 SDs from the nonspecific baseline established by the average of contaminant ribosomal proteins. Other proteins shown to be specifically enriched, but not correlated to gene transcription, are averaged together and listed individually in Table 4 and Table 5. The number of proteins averaged is shown in parentheses. The SD is indicated.

FIG. 6 depicts a plot showing the validation of proteins and histone post-translational modifications on GAL1 chromatin. ChIP was targeted to Gal3-TAP, Spt16-TAP, Rpb2-TAP, H3K14ac, and H3K36me3 under transcriptionally active galactose and repressive glucose growth conditions. ChIP to general H3 was used as a nucleosome occupancy control for each histone post-translational modification ChIP. Enrichment of the 5′ end of GAL1 DNA relative to ACT1 DNA was monitored by real-time PCR. The SE is indicated.

(FIG. 7A) Schematic overview of TAL-ChAP-MS technology. (FIG. 7B) A unique DNA sequence in the promoter region of GAL1 was used to design a specific binding TAL protein that contained a PrA affinity tag (SEQ ID NO:2). (FIG. 7C) A pTAL-PrA plasmid was introduced into S. cerevisiae cells, and the constitutive expression of the TAL-PrA fusion protein was confirmed by western blotting for PrA. (FIG. 7D) Expression of TAL-PrA does not impede galactose-induced GAL1 transcription. cDNA from wild-type yeast and wild-type with a plasmid expressing PrA-tagged TAL (+pTAL-PrA) grown in glucose (Glu) or galactose (Gal) was used as a template for real time PCR analysis of GAL1 versus ACT1 gene transcription. Error bars are the standard deviation. (FIG. 7E, FIG. 7F, FIG. 7G) TAL-PrA specifically binds and enriches chromatin at the promoter of transcriptionally active GAL1. ChIP was performed to the PrA-tag in wild-type cells containing the TAL-PrA (+pTAL-PrA, light gray bars) and in wild-type control (dark gray bars). The efficiency of GAL1 enrichment relative to ACT1 was monitored by real-time PCR with primers targeted to the TAL binding site (‘O’) and to DNA sequences 2000 by up- and downstream (FIG. 7E). The standard deviation is indicated. (FIG. 7F) Under transcriptionally active conditions (galactose), TAL-PrA specifically enriched chromatin from the GAL1 promoter region relative to sequences 2 kb up- and downstream. (FIG. 7G) The TAL-PrA protein did not show enrichment of the GAL1 promoter chromatin under transcriptionally repressive glucose growth conditions.

(FIG. 8A) Proteins co-purifying with TAL-PrA targeted to the promoter region of GAL1 (+pTAL-PrA lane) and proteins non-specifically associating with the IgG-coated Dynabeads (wild-type lane) were resolved by SDS-PAGE/Coomassie-staining and identified by high-resolution mass spectrometry. (FIG. 8B) Proteins found by label-free proteomic analysis to be enriched by >2-fold with transcriptionally active GAL1 promoter chromatin are plotted in accordance to their ranked level of enrichment divided by the total number of enriched proteins (N). Highlighted are the top 10% of proteins (>15-fold enrichment) and histone PTMs enriched with GAL1 promoter chromatin.

Enrichment adjacent to the TAL binding site in the promoter of GAL1 relative to ACT1 was monitored by real-time qPCR. The standard error is indicated.

FIG. 9 depicts an illustration of the CRISPR-ChAP-MS approach. PrA-tagged Cas9 bound to gRNA is targeted to a specific region of chromatin. Following chemical cross-linking, the chromatin is sheared to approximately 1 kb in size and subjected to affinity isolation with IgG-coated beads. Isolated chromatin containing PrA-tagged Cas9/gRNA is then analyzed with high resolution mass spectrometry to identify specifically associated proteins and histone posttranslational modifications.

(FIG. 10A) Using Western-blotting to the PrA-tag, similar expression of PrA-Cas9 was shown in both glucose and galactose-containing media. Western-blotting to histone H4 was used as a loading control. S. cerevisiae were transformed with either a plasmid expressing PrA-tagged Cas9 (pPrA-Cas9) and/or a plasmid expressing gRNA specific to a sequence in the promoter of GAL1 (pgRNA-GAL1). (FIG. 10B) Real-time reverse transcription PCR showed similar galactose-induced transcription of the GAL1 gene relative to ACT1 in cells expressing PrA-Cas9±gRNA-GAL1. Transcript levels of GAL1 are reported as a ratio of detection in galactose relative to glucose-containing media. (FIG. 10C) PrA-Cas9/gRNA complex specifically enriched GAL1 promoter chromatin under transcriptionally active conditions. Using ChIP to the PrA-tag on Cas9, enrichment at each indicated target relative to actin was measured in cells containing the PrA-Cas9/gRNA complex in comparison to those with only the PrA-Cas9. The genomic targets were: GAL1 for the genomic target of the gRNA-GAL1, 2000 base-pairs up- and downstream of the gRNA-GAL1 target, and four off-target (OT) sites for the PrA-Cas9/gRNA-GAL1 complex containing varying levels of sequence similarity to the gRNA-GAL1 target (±protospacer-activation motif (PAM motif)). Error bars are standard error from triplicate analyses. (*) indicates significant (p<0.05) enrichment from galactose growths relative to glucose.

FIG. 11A and FIG. 11B depict a SDS-PAGE gel and a graph showing CRISPR-ChAP-MS analysis of transcriptionally active promoter chromatin. (FIG. 11A) Chromatin was affinity purified on IgG-beads from cells grown in galactose-containing media that expressed PrA-Cas9 as a control and cells that expressed PrA-Cas9/gRNA targeted to the promoter region of GAL1. Co-enriched proteins were resolved by SDS-PAGE and identified with high resolution mass spectrometry. Label-free proteomics was used to determine whether a protein or histone PTM was specifically enriched with the promoter chromatin. (FIG. 11B) ChIP to PrA-tagged versions of the proteins or to the histone PTM (normalized for nucleosome occupancy) purified with the promoter chromatin was used to validate enrichment at the GAL1 promoter relative to ACT1. Cells were grown in either glucose or galactose-containing media.

DETAILED DESCRIPTION OF THE INVENTION

A method of isolating and identifying proteins associated with a target region of chromatin in a cell has been discovered. The method may also be used to identify post-translational modifications (PTMs) of proteins associated with a target chromatin in a cell. Advantageously, the method may be used to determine whether the association of the identified proteins with a chromatin in a cell is specific or non-specific. As used herein, “specifically associated” or “specific association” of a protein with a target chromatin refers to any protein in a cell that normally associates with a chromatin in a cell. In addition, and as illustrated in the examples, the method may be used to determine the role of proteins and post-translational modifications (PTMs) of proteins in chromatin function, including regulatory mechanisms of transcription, and the role of epigenomic factors in controlling chromatin function.

I. Method of ChAP-MS

In some aspects, the invention provides methods of isolating and identifying proteins specifically associated with a target chromatin. As described in Example 1 and FIG. 1, a method of the invention comprises isolating a target chromatin from a cell. As used herein, a “target chromatin” refers to a specific chromatin or a chromatin fragment that may be used in an application of the invention. According to the method, isolating the target chromatin isolates nucleic acid sequences and proteins, including proteins comprising posttranslational modifications, associated with the target chromatin. The proteins and posttranslational modifications of proteins associated with the target chromatin may then be identified, and a determination of which of the identified proteins and posttranslational modifications of proteins associated with a target chromatin isolated from a cell are specifically or non-specifically associated with the target chromatin is made.

To determine which of the identified proteins and posttranslational modifications of proteins associated with a target chromatin isolated from a cell are specifically or non-specifically associated with the target chromatin, a method of the invention provides two cell samples, or lysates derived from two cell samples, comprising the target chromatin, wherein proteins in one cell sample, but not both of the cell samples are metabolically labeled. Typically, the two cell samples are grown identically. In addition, the target chromatin in one of the cell samples or an extract from one of the cell samples is tagged. The two cell samples, or lysates derived from the cell samples of the invention are combined. The tagged target chromatin is isolated in the presence of the other cell sample or an extract from the other cell sample. Therefore, if a target chromatin of the invention is tagged in the unlabeled cell sample, proteins specifically associated with the tagged chromatin are unlabeled, and will be isolated in the presence of labeled proteins from the labeled cell sample. Alternatively, if a target chromatin of the invention is tagged in the labeled cell sample, the proteins associated with the tagged chromatin are labeled, and will be isolated in the presence of unlabeled proteins from the unlabeled cell sample.

As such, determining if a certain identified protein associated with the target chromatin is labeled, unlabeled, or a combination of labeled and unlabeled may determine if the protein was specifically associated with a target chromatin of the invention. If an identified protein comprises a mixture of labeled and unlabeled proteins, then that protein became associated with a target chromatin during the chromatin isolation procedure, and association of that protein with the target chromatin is not specific. If a target chromatin of the invention is isolated from the unlabeled cell sample, only unlabeled identified proteins associated with the target chromatin are specifically associated with the target chromatin. Alternatively, if a target chromatin of the invention is isolated from the labeled cell sample, only labeled identified proteins associated with the target chromatin are specifically associated with the target chromatin.

In some embodiments, a tagged target chromatin of the invention is isolated from an unlabeled cell sample, and unlabeled proteins associated with the target chromatin are specifically associated with the target chromatin. In other embodiments, a tagged target chromatin of the invention is isolated from a labeled cell sample, and labeled proteins associated with the target chromatin are specifically associated with the target chromatin.

As will be appreciated by a skilled artisan, the method of collecting a biological sample can and will vary depending upon the nature of the biological sample and the type of analysis to be performed. Any of a variety of methods generally known in the art may be utilized to collect a biological sample. Generally speaking, the method preferably maintains the integrity of the sample such that chromatin can be accurately detected and measured according to the invention.

As described in Section (I) above, two cell samples, or lysates derived from two cell samples are combined, and a tagged target chromatin of the invention is isolated from the combined cells or combined cell lysates. Typically, cells in two cell samples of the invention are from the same type of cells or they may be derived from the same type of cells. For instance, cells may comprise a heterologous nucleic acid in a target chromatin, and may also comprise a heterologous protein expressed in a cell of the invention. The heterologous nucleic acid in a target chromatin may be used for tagging a chromatin of the invention, and the heterologous protein expressed in a cell may be used for tagging a target chromatin as described in Section I(d). In some embodiments, cells in two cell samples of the invention are from the same type of cells. In other embodiments, cells in the first cell sample are derived from the same cell type as cells in the second cell sample.

Two cell samples of the invention may be from the same genus, species, variety or strain of cells. In preferred embodiments, two cell samples of the invention are Saccharomyces cerevisiae yeast cells or derivatives of Saccharomyces cerevisiae yeast cells. In exemplary embodiments, two cell samples of the invention are Saccharomyces cerevisiae W303a yeast cells or derivatives of Saccharomyces cerevisiae W303a yeast cells. In exemplary embodiments, two cell samples of the invention are derivatives of Saccharomyces cerevisiae W303a yeast cells comprising the lexA binding site upstream of the GAL1 transcription start site, wherein protein A is expressed in one of the cell samples of derived Saccharomyces cerevisiae W303a yeast cells.

According to the invention, a metabolically labeled cell sample and an unlabeled cell sample are combined to generate a combined cell sample, or lysates derived from the two cell samples are combined to generate a combined cell lysate. Cell samples may be combined in a weight to weight (w/w) ratio of about 1:100 to about 100:1, about 1:50 to about 50:1, about 1:25 to about 25:1, preferably about 1:10 to about 10:1, and more preferably about 1:5 to about 5:1. In preferred embodiments, cell samples are combined in a w/w ratio of about 1:5 to about 5:1, about 1:2 to about 2:1, about 1:1.5 to about 1.5:1, or about 1:1. In exemplary embodiments, cell samples are combined in a w/w ratio of about 1:1. If cell lysates derived from two cell samples of the invention are combined, lysates derived from cell ratios described herein are combined. Individuals of ordinary skill in the art will recognize that ratios of cell samples or lysates derived from cell samples described herein may be subject to statistical confidence limits of actual cell weight. For instance, the ratio may be based on 85, 90, 95% or more confidence limits on cell weight.

The number of cells in a cell sample can and will vary depending on the type of cells, the abundance of a target chromatin in a cell, and the method of protein identification used, among other variables. For instance, if a cell of the invention is Saccharomyces cerevisiae, about 5×10¹⁰ to about 5×10¹², more preferably, about 1×10¹¹ to about 1×10¹² cells may be used in a cell sample. In some embodiments, about about 1×10¹¹ to about 1×10¹² Saccharomyces cerevisiae cells are used in a cell sample.

Two cell samples of the invention are typically grown identically. Identically grown cell samples minimizes potential structural or functional differences at a target chromatin present in both cell samples. As used herein, “grown identically” refers to cultured cell samples grown using similar culture condition, or cells from a tissue harvested using identical harvesting techniques. As described below, the two cell samples of the invention are grown identically in a manner that allows the metabolic labeling of proteins in one of the cell samples. For instance, the two cell samples of the invention are grown identically, except that one of the cell samples may be grown in the presence of a labeled amino acid as described in the examples, to generate a cell sample with metabolically labeled proteins.

Proteins in a cell sample are metabolically labeled. Methods of metabolically labeling proteins in a cell are known in the art and may comprise culturing a cell in the presence of at least one labeled analogue of a biomolecule that is metabolized by a cell of the invention. When the labeled analog of a biomolecule is supplied to cells in culture instead of the unlabeled biomolecule, the labeled biomolecule is incorporated into all newly synthesized proteins. After a number of cell divisions, each instance of this particular labeled biomolecule will be replaced by its labeled analog. Since there is hardly any chemical difference between the labeled biomolecule and the unlabeled biomolecule, the cells behave exactly like the control cell population grown in the presence of unlabeled biomolecule. As such, up to 100% of the particular biomolecule in a cell may be labeled. In some embodiments, up to 10, 20, 30, 40, 50, 60, 70, 80, 90 or up to 100% of the particular biomolecule in a cell is labeled. In preferred embodiments, up to 50, 60, 70, 80, 90 or up to 100%, and more preferably up to 90 or up to 100% of the particular biomolecule in a cell is labeled.

(b) Chromatin

A method of the invention comprises identification of a protein and post-translational modification of a protein associated with a target chromatin. Generally, chromatin refers to the combination of nucleic acids and proteins in the nucleus of a eukaryotic cell. However, it is contemplated that the term “chromatin” may also refer to the combination of any nucleic acid sequence and proteins associated with the nucleic acid sequence in any cell.

A chromatin of the invention may comprise single stranded nucleic acid, double stranded nucleic acid, or a combination thereof. In some embodiments, a chromatin comprises single stranded nucleic acid. In other embodiments, a chromatin comprises a combination of single stranded and double stranded nucleic acids. In yet other embodiments, a chromatin comprises double stranded nucleic acid.

A chromatin of the invention may comprise a ribonucleic acid (RNA), a deoxyribonucleic acid (DNA), or a combination of RNA and DNA. In some embodiments, a chromatin of the invention comprises a combination of a RNA sequence and proteins associated with the RNA sequence in a cell. Non-limiting examples of RNA sequences may include mRNA, and non-coding RNA such as tRNA, rRNA, snoRNAs, microRNAs, siRNAs, piRNAs and the long noncoding RNA (IncRNA). In preferred embodiments, a chromatin of the invention comprises a combination of a DNA sequence and proteins associated with the DNA sequence in a cell. In other preferred embodiments, a chromatin of the invention comprises a combination of RNA and DNA sequences, and proteins associated with the RNA and DNA sequence in a cell. Non limiting examples of chromatin that may comprise a combination of RNA and DNA may include genomic DNA undergoing transcription, or genomic DNA comprising non-coding RNA such as IncRNA.

A chromatin of the invention may be genomic chromatin such as, chromatin from a chromosome of a cell, or chromatin from an organelle in the cell. Alternatively, a chromatin may be chromatin from an extrachromosomal nucleic acid sequence. In some embodiments, a chromatin of the invention is chromatin from an organelle in the cell. Non-limiting examples of a chromatin from an organelle may include mitochondrial nucleic acid sequence in plant and animal cells, and a chloroplast nucleic acid sequence in plant cells. In some embodiments, a nucleic acid sequence of the invention is a mitochondrial nucleic acid sequence. In other embodiments, a nucleic acid sequence of the invention is a chloroplast nucleic acid sequence.

In some embodiments, a chromatin of the invention is chromatin from an extrachromosomal nucleic acid sequence. The term “extrachromosomal,” as used herein, refers to any nucleic acid sequence not contained within the cell's genomic nucleic acid sequence. An extrachromosomal nucleic acid sequence may comprise some sequences that are identical or similar to genomic sequences in the cell, however, an extrachromosomal nucleic acid sequence as used herein does not integrate with genomic sequences of the cell. Non-limiting examples of an extrachromosomal nucleic acid sequence may include a plasmid, a virus, a cosmid, a phasmid, and a plasmid.

In some preferred embodiments, a chromatin of the invention is genomic chromatin. In exemplary embodiments, a chromatin of the invention is genomic chromatin of a eukaryotic cell. A eukaryotic cell of the invention may be as described in Section I(a) above.

Primary functions of genomic chromatin of a eukaryotic cell may be DNA packaging into a smaller volume to fit in the cell, strengthening of the DNA to allow mitosis, prevent DNA damage, and to control gene expression and DNA replication. As described above, genomic chromatin of a eukaryotic cell may comprise DNA sequences and a plurality of DNA-binding proteins as well as certain RNA sequences, assembled into higher order structural or functional regions. As used herein, a “structural or functional feature of a chromatin”, refers to a chromatin feature characterized by, or encoding, a function such as a regulatory function of a promoter, terminator, translation initiation, enhancer, etc., or a structural feature such as heterochromatin, euchromatin, a nucleosome, a telomere, or a centromere. A physical feature of a nucleic acid sequence may comprise a functional role and vice versa. As described below, a chromatin of the invention may be a chromatin fragment, and as such may comprise a fragment of a physical or functional feature of a chromatin, or no physical or functional features or known physical or functional features.

The primary protein components of genomic eukaryotic chromatin are histones that compact the DNA into a nucleosome. The nucleosome comprises an octet of histone proteins around which is wound a stretch of double stranded DNA sequence of about 150 to about 250 bp in length. Histones H2A, H2B, H3 and H4 are part of the nucleosome while histone H1 may act to link adjacent nucleosomes together into a higher order structure. Histones are subject to post translational which may affect their function in regulating chromatin function. Such modifications may include methylation, citrullination, acetylation, phosphorylation, SUMOylation, ubiquitination, and ADP-ribosylation.

Many further polypeptides and protein complexes interact with the nucleosome and the histones to regulate chromatin function. A “polypeptide complex” as used herein, is intended to describe proteins and polypeptides that assemble together to form a unitary association of factors. The members of a polypeptide complex may interact with each other via non-covalent or covalent bonds. Typically members of a polypeptide complex will cooperate to enable binding either to a nucleic acid sequence or to polypeptides and proteins already associated with or bound to a nucleic acid sequence in chromatin. Chromatin associated polypeptide complexes may comprise a plurality of proteins and/or polypeptides which each serve to interact with other polypeptides that may be permanently associated with the complex or which may associate transiently, dependent upon cellular conditions and position within the cell cycle. Hence, particular polypeptide complexes may vary in their constituent members at different stages of development, in response to varying physiological conditions or as a factor of the cell cycle. By way of example, in animals, polypeptide complexes with known chromatin remodelling activities include Polycomb group gene silencing complexes as well as Trithorax group gene activating complexes.

Additionally, a protein associated with a chromatin of the invention may be a protein normally expressed in a cell, or may be an exogenous heterologous protein expressed in a cell. In some embodiments, a protein associated with a chromatin of the invention is a protein normally expressed in a cell. In other embodiments, a protein associated with a chromatin of the invention is a protein not normally expressed in a cell.

A chromatin of the invention may be an intact and complete chromatin from the cell, or may be a fragment of a chromatin in a cell. In some embodiments, a chromatin of the invention is an intact chromatin isolated from a cell. For instance, a chromatin of the invention may be a plasmid, a cosmid, or a phage chromatin or a complete organellar chromatin. In preferred embodiments, a chromatin of the invention is a fragment of a chromatin from a cell. In exemplary embodiments, a chromatin of the invention is a fragment of a genomic chromatin from a cell.

When a chromatin of the invention is a fragment of a chromatin in a cell, any method of fragmenting a chromatin known in the art may be used. Such methods may include physical methods of fragmenting a chromatin, or enzymatic digestion of a nucleic acid sequence of a chromatin. In some embodiments, a fragment of a chromatin may be generated using enzymatic digestion of a nucleic acid sequence in chromatin. Non-limiting examples of enzymatic digestion may include random or sequence specific enzymatic digestion using restriction enzymes, nucleases, combinations of restriction enzymes and nucleases, or combinations of nicking and other nucleases such as NEBNext™ fragmentase, which comprises a nicking enzyme that randomly generates nicks in double stranded DNA and another enzyme that cuts the strand opposite to the generated nicks.

In other embodiments, a fragment of a chromatin may be generated using a physical method of fragmenting a chromatin. Non-limiting examples of physical fragmenting methods that may be used to fragment a chromatin of the invention may include nebulization, sonication, and hydrodynamic shearing.

(c) Preparation of Cell Lysate

A target chromatin is isolated from a combined cell lysate. A combined cell lysate comprises a lysate of two combined cell samples, or a combination of two cell lysates derived from two cell samples, wherein a target chromatin is tagged in one of the cell samples. Irrespective of whether one cell sample or a combined cell sample is lysed, a skilled practitioner of the art will appreciate that structural and functional features of a target chromatin must be preserved during cell lysis and isolation of the target chromatin. The association of proteins with a target chromatin may be preserved during cell lysis and isolation of the target chromatin using methods known in the art for preserving a complex of proteins with a nucleic acid sequence. For instance, lysing of a cell and isolation of a target chromatin may be performed under refrigeration or using cryogenic methods and buffer conditions capable of preserving association of proteins and nucleic acid sequences. In addition, a complex of proteins with a nucleic acid may be preserved by crosslinking protein and nucleic acid complexes in a cell prior to lysing and isolating a chromatin. Crosslinking protein and nucleic acid complexes in a cell may also capture, or preserve, transient protein-protein and protein-nucleic acid interactions.

In some embodiments, a complex of proteins with a nucleic acid may be preserved by crosslinking protein and nucleic acid complexes in a chromatin prior to lysing a cell and isolating the chromatin. Crosslinking is the process of joining two or more molecules such as two proteins or a protein and a nucleic acid molecule, by a covalent bond. Molecules may be crosslinked by irradiation with ultraviolet light, or by using chemical crosslinking reagents. Chemical crosslinking reagents capable of crosslinking proteins and nucleic acids are known in the art and may include crosslinking reagents that target amines, sulfhydryls, carboxyls, carbonyls or hydroxyls; omobifunctional or heterobifunctional crosslinking reagent, variable spacer arm length or zero-length crosslinking reagents, cleavable or non-cleavable crosslinking reagents, and photoreactive crosslinking reagents. Non-limiting examples of crosslinking reagents that may be used to crosslink protein complexes and/or protein complexes and nucleic acids may include formaldehyde, glutaraldehyde, disuccinimidyl glutarate, disuccinimidyl suberate, a photoreactive amino acid such as photo-leucine or photo-methionine, and succinimidyl-diazirine. The degree of crosslinking can and will vary depending on the application of a method of the invention, and may be experimentally determined.

In a preferred embodiment, a complex of proteins with a nucleic acid in a chromatin of the invention may be preserved by crosslinking protein and nucleic acid complexes in a cell prior to lysing using formaldehyde. In an exemplary embodiment, a complex of proteins with a nucleic acid in a chromatin of the invention may be preserved by crosslinking protein and nucleic acid complexes in a cell prior to lysing using formaldehyde as described in the examples.

A skilled practitioner of the art will appreciate that protocols for lysing a cell can and will vary depending on the type of cell, the target chromatin of the invention, and the specific application of a method of the invention. Non limiting examples of methods that may be used to lyse a cell of the invention may include cell lysis using a detergent, an enzyme such as lysozyme, incubation in a hypotonic buffer which causes a cell to swell and burst, mechanical disruption such as liquid homogenization by forcing a cell through a narrow space, sonication, freeze/thaw, mortar and pestle, glass beads, and combinations thereof. In some embodiments, when a cell of the invention is a yeast cell, the cell may be cryogenically lysed under liquid nitrogen temperature with glass beads. In exemplary embodiments, when a cell of the invention is a yeast cell, the cell may be cryogenically lysed under liquid nitrogen temperature with glass beads as described in the examples.

Buffer conditions used during lysing and isolation of a chromatin of the invention can and will be altered to control stringent conditions during cell lysis and isolation to preserve association of proteins and nucleic acid sequences of a chromatin. “Stringent conditions” in the context of chromatin isolation are conditions capable of preserving specific association of proteins and nucleic acids of a chromatin, but minimizing non-specific association of proteins and nucleic acids. Stringent condition can and will vary depending on the application of a method of the invention, the target chromatin of the invention, the nucleic acid sequence in a target chromatin, the proteins or protein complexes associated with a target chromatin of the invention, whether or not proteins, protein complexes and nucleic acid sequences are crosslinked, and the conditions used for crosslinking proteins, protein complexes and nucleic acid sequences of a target chromatin. For instance, more stringent buffer conditions may be used in a method of the invention wherein proteins, protein-protein complexes, and protein-nucleic acid complexes are crosslinked compared to a method of the invention wherein proteins, protein-protein complexes, and protein-nucleic acid complexes are not crosslinked. As such, stringent buffer conditions used during cell lysis and isolation of a nucleic acid sequence of the invention may be experimentally determined for each application wherein a method of the invention is used. Buffer conditions that may alter stringent conditions during cell lysis and isolation may include pH and salt concentration. In preferred embodiments, proteins, protein-protein complexes, and protein-nucleic acid complexes of a target chromatin of the invention are crosslinked, and stringent buffer conditions are used during lysis and isolation of a chromatin of the invention. In exemplary embodiments, proteins, protein-protein complexes, and protein-nucleic acid complexes of a target chromatin of the invention are crosslinked, and stringent buffer conditions are used during lysis and isolation of a chromatin of the invention and are as described in the examples.

(d) Chromatin Isolation

According to the invention, a tagged target chromatin is isolated from a combined cell lysate. As described in Sections I(a) and I(c) above, a combined cell lysate comprises a lysate of two combined cell samples, or a combination of two cell lysates derived from two cell samples, wherein a target chromatin is tagged in one of the lysates, or one of the cell samples. As such, a target chromatin is isolated from a cell lysate comprising a combination of a tagged target chromatin and an untagged target chromatin. The ratio of tagged target chromatin to untagged target chromatin reflects the ratio at which the two cell samples or the lysates derived from the two cell sample are combined. In addition, proteins in one of the cell samples or lysate derived from one of the cell samples are metabolically labeled. Therefore, when a tagged target chromatin is from a cell sample wherein proteins are metabolically labeled, a cell lysate of the invention comprises a combination of a tagged target chromatin comprising metabolically labeled proteins, and an untagged target chromatin comprising unlabeled proteins. Conversely, when a tagged target chromatin is from a cell sample wherein proteins are unlabeled, a cell lysate of the invention comprises a combination of a tagged target chromatin comprising unlabeled proteins, and an untagged target chromatin comprising labeled proteins.

A target chromatin may be isolated from a mixture of chromatins or chromatin fragments in a cell lysate as described in this section. As used herein, a target nucleic acid sequence is said to be “isolated” or “purified” when it is substantially free of proteins not associated with the target chromatin, nucleic acid sequences other than the nucleic acid sequences associated with the target chromatin, and other cell debris and cell contents resulting from extraction and preparation of the target chromatin from a cell. A target chromatin of the present invention may be purified to homogeneity or other degrees of purity. In general, the level of purity of an isolated target chromatin can and will vary depending on the cell type, the specific chromatin to be isolated, and the intended use of a target chromatin of the invention. The level of purity of an isolated target chromatin may be determined using methods known in the art. For instance, the level of purity of an isolated target chromatin may be determined by determining the level of purity of a nucleic acid sequence associated with a target chromatin, by determining the level of purity of a protein associated with a target chromatin, or by determining the level of enrichment of a target chromatin, compared to a non-target chromatin in a cell. In preferred embodiments, the level of purity of an isolated target chromatin is determined by determining the level of enrichment of a target chromatin, compared to a non-target chromatin in a cell. Determining the level of enrichment of a target chromatin, compared to a non-target chromatin in a cell may be as described in this section below.

A target chromatin of the invention may be isolated using methods known in the art, such as electrophoresis, molecular, immunological and chromatographic techniques, ion exchange, hydrophobic, affinity, and reverse-phase HPLC chromatography, size exclusion chromatography, precipitation, dialysis, chromatofocusing, ultrafiltration and diafiltration techniques, and combinations thereof. For general guidance in suitable purification techniques, see Scopes, R., Protein Purification, Springer-Vertag, NY (1982).

In general, a method of the invention comprises isolating a target chromatin by affinity purification, or affinity purification in combination with other methods of isolating chromatin described above. In a preferred embodiment, a method of the invention comprises isolating a target chromatin by affinity purification. Non limiting examples of affinity purification techniques that may be used to isolate a target chromatin of the invention may include affinity chromatography, immunoaffinity chromatography, size exclusion chromatography, and combinations thereof. See, for example, Roe (ed), Protein Purification Techniques: A Practical Approach, Oxford University Press, 2nd edition, 2001.

In essence, affinity purification of a target chromatin may comprise tagging a target chromatin by contacting the target chromatin of the invention with a tag capable of specifically recognizing and binding one or more portions of a target chromatin. As used herein, “specifically recognizing” refers to a binding reaction between two separate molecules that is at least two times the background and more typically more than 10 to 100 times the background molecular associations under physiological conditions. As described in Section (I), two cell samples, or lysates derived from the cell samples of the invention are combined, and a target chromatin in one of the cell samples or an extract from one of the cell samples is tagged. In addition, proteins in one cell sample, but not both of the cell samples are metabolically labeled. As such, a target chromatin may be tagged in a cell or an extract from a cell wherein proteins are metabolically labeled, and proteins specifically associated with an isolated target chromatin are metabolically labeled. Alternatively, a target chromatin may be tagged in a cell or an extract from a cell wherein proteins are not metabolically labeled, and proteins specifically associated with an isolated target chromatin are not metabolically labeled. In some embodiments, a target chromatin is tagged in a cell or an extract from a cell wherein proteins are metabolically labeled. In other embodiments, a target chromatin is tagged in a cell or an extract from a cell wherein proteins are metabolically labeled.

A tag may be capable of specifically recognizing and binding 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 components of a target chromatin. In preferred embodiments, a tag is capable of specifically recognizing and binding one component of a target chromatin.

A tag may be capable of specifically recognizing and binding a component in a target chromatin. A component in a target chromatin may be a nucleic acid sequence in a nucleic acid associated with a target chromatin, a protein associated with a target chromatin, or a chromatin structural or functional feature in a target chromatin. In some embodiments, a tag is capable of specifically recognizing and binding a protein associated with a target chromatin. In other embodiments, a tag is capable of specifically recognizing and binding a chromatin structural or functional feature in a target chromatin. In preferred embodiments, a tag is capable of specifically recognizing and binding a nucleic acid sequence associated with a target chromatin.

A nucleic acid sequence associated with a target chromatin that may be specifically recognized and bound by a tag of the invention may be a nucleic acid sequence normally found in a chromatin of a cell of the invention. Alternatively, a nucleic acid sequence associated with a target chromatin that may be specifically recognized and bound by a tag of the invention may be an exogenous nucleic acid sequence introduced into a cell to facilitate tagging a target chromatin of the invention. In some embodiments, a nucleic acid sequence that may be recognized and bound by a tag is a nucleic acid sequence normally found in a chromatin of a cell of the invention. In other embodiments, a nucleic acid sequence that may be recognized and bound by a tag of the invention is an exogenous nucleic acid sequence introduced into a cell of the invention to facilitate tagging a chromatin of the invention. Non limiting examples of an exogenous nucleic acid sequence introduced into a cell to facilitate tagging a target chromatin of the invention may be the lexA binding sequence, and the Lac operator. In a preferred embodiment, a heterologous nucleic acid sequence introduced into a cell to facilitate tagging a target nucleic acid sequence of the invention is the lexA binding sequence. In an exemplary embodiment, a heterologous nucleic acid sequence introduced into a cell to facilitate tagging a target nucleic acid sequence of the invention is the lexA binding sequence immediately upstream of the transcription start site.

Individuals of ordinary skill in the art will recognize that an exogenous chromatin component introduced into a cell to facilitate tagging a target chromatin of the invention cannot and will not disrupt a target chromatin, or a structural or functional feature of a target chromatin. Methods of designing a chromatin component and a tag capable of binding the chromatin component that do not disrupt a chromatin of the invention may depend on the particular application of a method of the invention, and may be determined experimentally. For instance, if an application of a method of the invention comprises promoter function, a tag may be designed to bind anywhere adjacent to the promoter, but without disrupting the promoter.

A tag of the invention may further comprise one or more affinity handles. As used herein, the term “affinity handle” may refer to any handle that may be bound by a substrate for affinity purification, as described below. A tag may comprise one or more than one affinity handle. The inclusion of more than one affinity handle in a tag of the invention may significantly increase the efficiency of affinity purification for a low copy number chromatin target. As such, a tag may further comprise 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more affinity handles. In a preferred embodiment, a tag of the invention comprises one affinity handle.

Affinity handles may include any affinity handle for which a cognate binding agent is readily available. An affinity handle may be an aptamer, an antibody, an antibody fragment, a double-stranded DNA sequence, modified nucleic acids and nucleic acid mimics such as peptide nucleic acids, locked nucleic acids, phosphorodiamidate morpholino oligomers (PMO), a ligand, a ligand fragment, a receptor, a receptor fragment, a polypeptide, a peptide, a coenzyme, a coregulator, an allosteric molecule, non-immunoglobulin scaffolds such as Affibodies, Anticalins, designed Ankyrin repeat proteins and others, an ion, or a small molecule for which a cognate binding agent is readily available. The term “aptamer” refers to a polypeptide or a polynucleotide capable of binding to a target molecule at a specific region. It is generally accepted that an aptamer, which is specific in its binding to any polypeptide, may be synthesized and/or identified by in vitro evolution methods. Non limiting examples of handles that may be suitable for isolating a chromatin may include biotin or a biotin analogue such as desthiobiotin, digoxigenin, dinitrophenol or fluorescein, a macromolecule that binds to a nucleic acid or a nucleic acid binding protein such as the Lac repressor, a zinc finger protein, a transcription activator protein capable of binding a nucleic acid, or a transcription activator-like (TAL) protein, antigenic polypeptides such as protein A, or peptide ‘tags’ such as polyhistidine, FLAG, HA and Myc tags. In preferred embodiments, a tag of the invention comprises an antigenic polypeptide. In exemplary embodiments, a tag of the invention comprises the protein A antigenic polypeptide, or derivatives thereof. Protein A is capable of binding the lexA binding site, and comprises an affinity handle capable of binding IgG. As such, protein A may be used as an affinity purification tag for purifying a target chromatin comprising a lexA binding tag.

In some embodiments, a tag of the invention is a nucleic acid tag capable of binding a nucleic acid sequence component of a chromatin, wherein the nucleic acid sequence component of the chromatin is introduced into a cell of the invention. In some embodiments, a tag of the invention is a nucleic acid tag capable of binding a nucleic acid sequence component of a chromatin, wherein the nucleic acid sequence component of the chromatin is normally present in a cell of the invention. Non-limiting examples of nucleic acid tags capable of binding a nucleic acid sequence component of a chromatin include antisense RNA or DNA nucleic acid tags, and tags comprising modified nucleic acids and nucleic acid mimics such as peptide nucleic acids, locked nucleic acids, phosphorodiamidate morpholino oligomers (PMO). In some embodiments, a tag of the invention is a nucleic acid tag comprising locked nucleotides. For instance, a nucleic acid tag comprising locked nucleotides may be as described in US20110262908 or US20120040857, and a peptide nucleic acid tag may be as described in Boffa et al. 1995 PNAS 92:1901-1905, the disclosures of all of which are incorporated herein in their entirety.

In some preferred embodiments, a tag of the invention is a protein tag capable of binding a nucleic acid sequence component of a chromatin, wherein the nucleic acid sequence component of the chromatin is a nucleic acid sequence normally found in a chromatin of a cell of the invention. Non limiting examples of a protein tag capable of binding a nucleic acid sequence normally found in a chromatin of a cell may be a nucleic acid binding protein such as protein A, the Lac repressor, a zinc finger protein, a transcription activator protein capable of binding a nucleic acid, or a transcription activator-like (TAL) protein. In one embodiment, a tag of the invention is a transcription activator protein capable of binding a nucleic acid sequence normally found in a chromatin of a cell of the invention. In another embodiment, a tag of the invention is a zinc finger protein capable of binding a nucleic acid sequence normally found in a chromatin of a cell of the invention. In yet another embodiment, a tag of the invention is a transcription activator-like (TAL) protein capable of binding a nucleic acid sequence normally found in a chromatin of a cell of the invention.

A nucleic acid binding protein tag of the invention may be a wild type nucleic acid binding protein capable of binding a nucleic acid sequence normally found in a target chromatin. Alternatively, a nucleic acid binding protein tag of the invention may be engineered to have binding specificity for a nucleic acid sequence component normally found in a target chromatin of the invention. Individuals of ordinary skill in the art will recognize that nucleic acid binding proteins such as zinc finger proteins, transcription activator proteins, and transcription activator-like (TAL) proteins may be engineered to have novel nucleic acid binding specificity compared to naturally-occurring forms of the proteins. See, for example, U.S. Pat. Nos. 6,453,242 and 6,534,261, and U.S. Pate. Appl. Nos 20110239315, 20120110685, and 20120270273, the disclosures of which are incorporated by reference herein in their entireties. In some embodiments, a nucleic acid binding protein tag of the invention is a wild type nucleic acid binding protein capable of binding a nucleic acid sequence normally found in a target chromatin. In other embodiments, a nucleic acid binding protein tag of the invention is a nucleic acid binding protein engineered to have binding specificity for a nucleic acid sequence component of a target chromatin of the invention. In a preferred embodiment, a nucleic acid binding protein tag of the invention is a zinc finger protein engineered to have binding specificity for a nucleic acid sequence component of a target chromatin of the invention. In another preferred embodiment, a nucleic acid binding protein tag of the invention is a TAL protein engineered to have binding specificity for a nucleic acid sequence component of a target chromatin of the invention.

In other preferred embodiments, a tag of the invention is a protein tag capable of binding a nucleic acid sequence component of a chromatin, wherein the nucleic acid sequence component of the chromatin is an exogenous nucleic acid sequence introduced into a cell of the invention. In exemplary embodiments, a tag of the invention is a protein A tag capable of binding the lexA exogenous nucleic acid sequence introduced in a cell of the invention. In an exemplary embodiment, a tag of the invention is a protein A tag capable of binding the lexA exogenous nucleic acid sequence introduced upstream of the transcriptional start site of the GAL1 promoter of a S. cereviseae cell as described in the examples.

A target chromatin may be contacted with a tag at any time during a method of the invention leading to isolation of target chromatin. For instance, a target chromatin may be contacted with a protein tag during cell culture by expressing the protein tag in a cell of the invention. Alternatively, a target chromatin may be contacted with a tag after cell culture but before cell lysis, after cell lysis, or after fragmentation of chromatin to generate chromatin fragments comprising a target chromatin.

In some embodiments, a target chromatin is contacted with a tag after cell culture but before cell lysis. As such, a tag may be introduced into a cell before cell lysis. Methods of introducing a tag into a cell of the invention can and will vary depending on the type of cell, the tag, and the application of a method of the invention. For instance, a nucleic acid tag may be electroporated into a cell after culture. In other embodiments, a target chromatin is contacted with a tag after cell lysis. In such an embodiment, a tag may be added to the cell lysate as a recombinant protein. The recombinant protein may be expressed, isolated and purified via methods standard in the art for protein purification. In yet other embodiments, a target chromatin is contacted with a tag after cell lysis and chromatin fragmentation. In preferred embodiments, a target chromatin is contacted with a tag during cell culture by expressing the tag in a cell of the invention during cell culture. In exemplary embodiments, a target chromatin comprises the lexA binding site, and the lexA binding site is contacted with a protein A tag during cell culture by expressing the protein A in a cell of the invention during cell culture. In an exemplary embodiment, a target chromatin comprises the lexA binding site, and the lexA binding site is contacted with a protein A tag during cell culture by expressing the protein A in a yeast cell of the invention during cell culture as described in the examples.

A target chromatin contacted and bound by a tag as described above may be isolated using an affinity handle of the tag. The term “isolated”, may be used herein to describe a purified preparation of a target chromatin that is enriched for the target chromatin, but wherein the target chromatin is not necessarily in a pure form. That is, an isolated target chromatin is not necessarily 100% pure, but may be about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90% pure. An isolated target chromatin may be enriched for the target chromatin, relative to a chromatin in the lysed preparation that was not contacted by a tag of the invention. An isolated target chromatin may be enriched by 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 fold relative to a chromatin that is not contacted by a tag of the invention. In some embodiments, an isolated target chromatin is enriched by 2, 3, 4, or 5 fold relative to a chromatin that was not contacted by a tag of the invention. In other embodiments, an isolated target chromatin is enriched by 5, 6, 7, 8, 9, or 10 fold relative to a chromatin that was not contacted by a tag of the invention. In an exemplary embodiment, an isolated target chromatin is enriched 4, 5, or 6 fold relative to a chromatin that was not contacted by a tag of the invention.

A target chromatin contacted and bound by a tag as described above may be isolated using any affinity purification method known in the art. In short, a tagged target chromatin is bound to a substrate capable of binding the affinity handle. The substrate comprising a bound target chromatin may then be washed to remove non-target chromatin and other cell debris, and the target chromatin may be released from substrate. Methods of affinity purification of material comprising an affinity handle are known in the art and may include binding the affinity handle to a substrate capable of binding the affinity handle. The substrate may be a gel matrix such as gel beads, the surface of a container, or a chip. The tagged target chromatin bound to the substrate may then be purified. Methods of purifying tagged molecules are known in the art and will vary depending on the target molecule, the tag, and the substrate. For instance, if the tag is a protein A tag bound to a lexA binding site in a target chromatin, the target chromatin may be bound to a magnetic bead substrate comprising IgG, and purified using a magnet.

(e) Protein Extraction, Identification, and Determination of Labeling

Proteins and peptides associated with an isolated target chromatin are extracted from the isolated target chromatin. Methods of extracting proteins from chromatin are generally known in the art of protein biochemistry. Generally, any extraction protocol suitable for isolating proteins and known to those of skill in the art may be used. Extracted proteins may also be further purified before protein identification. For instance, protein extracts may be further purified by differential precipitation, differential solubilization, ultracentrifugation, using chromatographic methods such as size exclusion chromatography, hydrophobic interaction chromatography, ion exchange chromatography, affinity chromatography, metal binding, immunoaffinity chromatography, HPLC, or gel electrophoriesis such as SDS-PAGE and QPNC-PAGE. In a preferred embodiment, extracted proteins are further purified using SDS-PAGE.

Extracted and purified intact proteins and post-translational modification of proteins may then be identified. Alternatively, extracted and purified intact proteins may be further digested, and the resulting peptide fragments are identified. In some embodiments, intact extracted proteins are identified. In preferred embodiments, extracted proteins are further digested, and the resulting peptide fragments are identified. For instance, protein extracts may be fragmented by enzymatically digesting the proteins using a protease such as trypsin. In exemplary embodiments, extracted proteins are further digested as described in the examples.

Methods of identifying proteins or protein fragments are known in the art and may include mass spectrometry (MS) analysis, or a combination of mass spectrometry with a chromatographic technique. Non limiting examples of mass spectrometer techniques may include tandem mass spectrometry (MS/MS), matrix-assisted laser desorption/ionization source with a time-of-flight mass analyzer (MALDI-TOF), inductively coupled plasma-mass spectrometry (ICP-MS), accelerator mass spectrometry (AMS), thermal ionization-mass spectrometry (TIMS), isotope ratio mass spectrometry (IRMS), and spark source mass spectrometry (SSMS). Chromatographic techniques that may be used with MS may include gas chromatography, liquid chromatography, and ion mobility spectrometry. In a preferred embodiment, proteins may be identified using tandem mass spectrometry in combination with liquid chromatography (LC-MS/MS). In another preferred embodiment, post-translational modification of proteins may be identified using tandem mass spectrometry in combination with liquid chromatography (LC-MS/MS).

As described above, proteins isolated with a chromatin of the invention may be labeled, unlabeled or a combination of labeled and unlabeled proteins. As described in Section I(d), if a target chromatin is tagged in a cell or an extract from a cell wherein proteins are metabolically labeled, proteins specifically associated with an isolated target chromatin are metabolically labeled, whereas unlabeled proteins, or proteins comprising a combination of labeled and unlabeled proteins are not specifically associated with the target chromatin. Alternatively, if a target chromatin may be tagged in a cell or an extract from a cell wherein proteins are not metabolically labeled, proteins specifically associated with an isolated target chromatin are metabolically labeled, whereas unlabeled proteins, or proteins comprising a combination of labeled and unlabeled proteins are not specifically associated with the target chromatin.

When an isolated and identified protein is a combination of labeled and unlabeled protein, the ratio of labeled to unlabeled protein may reflect a ratio at which a metabolically labeled cell sample and an unlabeled cell sample are combined to generate a combined cell sample, or lysates derived from the two cell samples are combined to generate a combined cell lysate. For instance, if a metabolically labeled cell sample and an unlabeled cell sample, or lysates derived from the two cell samples, are combined at a ratio of 1:1, the ratio of labeled to unlabeled isolated protein may be 1:1.

However, since the ratio of labeled to unlabeled isolated protein depends on the rate of exchange of the identified protein during extraction and processing of a cell sample, a ratio of labeled to unlabeled isolated protein may differ from the ratio at which a metabolically labeled cell sample and an unlabeled cell sample are combined to generate a combined cell sample, or lysates derived from the two cell samples are combined to generate a combined cell lysate. For example, if a metabolically labeled cell sample and an unlabeled cell sample, or lysates derived from the two cell samples, are combined at a ratio of 1:1, a ratio of labeled to unlabeled isolated protein may deviate from a ratio of 1:1. As such, a ratio of labeled to unlabeled isolated protein may be compared to a baseline for non-specifically associated proteins. For instance, a baseline for non-specifically associated proteins may be a ratio of labeled to unlabeled of one or more proteins in a combined lysate, wherein the one or more proteins are not associated with a chromatin. Non-limiting examples of proteins not associated with a chromatin may include enzymes required for metabolism, receptors, and ribosomal proteins. In preferred embodiments, proteins not associated with a chromatin are ribosomal proteins, and a baseline for non-specifically associated proteins is a ratio of a labeled to unlabeled ribosomal protein, or an average of ratios of labeled to unlabeled ribosomal proteins. In a preferred embodiment, proteins not associated with a chromatin are 20 ribosomal proteins, and a baseline for non-specifically associated proteins is an average of ratios of the 20 labeled to unlabeled ribosomal proteins.

Isolated proteins with a ratio of labeled to unlabeled isolated protein may be specifically associated with a chromatin if the ratio of labeled to unlabeled isolated protein is significantly different from a baseline ratio. A significantly different ratio may be a ratio of labeled to unlabeled isolated protein greater than about 1, 2, 3, 4, 5, or more standard deviations than a baseline ratio. In some embodiments, a significantly different ratio is a ratio of labeled to unlabeled isolated protein greater than about 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, or more standard deviations than a baseline ratio. In other embodiments, a significantly different ratio is a ratio of labeled to unlabeled isolated protein greater than about 1, 1.5, 2, or about 2.5 standard deviations than a baseline ratio. In preferred embodiments, a significantly different ratio is a ratio of labeled to unlabeled isolated protein greater than about 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9 or about 3 standard deviations than a baseline ratio. In exemplary embodiments, a significantly different ratio is a ratio of labeled to unlabeled isolated protein greater than about 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, or about 2.5 standard deviations than a baseline ratio.

Methods of determining if a protein or a protein fragment is labeled can and will vary depending on the type of label. For instance, if a protein is labeled using a tag, labeling may be determined using methods designed to detect the tag. For example, determining if a protein comprising a his-tag is tagged, untagged, or a combination of tagged and untagged may be by detecting the proteins comprising the his tag. If a protein is labeled using a radioactive isotope, labeling may be determined by determining the degree of radioactivity of isolated proteins or protein fragments. Alternatively, if a protein is labeled using a heavy isotope, MS analysis may be used to determine if a protein or a protein fragment is labeled or unlabeled. Advantageously, when a protein is labeled using a heavy isotope, MS analysis may be used to identify a protein or a protein fragment as described above, and to derive the MS data to determine if a protein or a protein fragment is labeled, unlabeled, or a combination of labeled and unlabeled protein or protein fragment.

In preferred embodiments, a protein is labeled using a heavy isotope, and MS analysis is used to identify a protein or a protein fragment, and to determine if a protein or a protein fragment is labeled, unlabeled, or a combination of labeled and unlabeled protein or protein fragment. Methods of deriving MS data to determine if a protein or a protein fragment is labeled, unlabeled, or a combination of labeled and unlabeled protein or protein fragment are known in the art, and may include using known computational techniques to distill MS data such as Mascot Distiller, Rosetta Elucidator, and MaxQuant. In some embodiments, MS data is derived using Rosetta Elucidator. In other embodiments, MS data is derived using MaxQuant. In preferred embodiments, MS data is derived using Mascot Distiller.

II. Method of TAL-ChAP-MS

In another aspect, the invention provides a method of isolating and identifying proteins specifically associated with a target chromatin using the TAL protein as described in Example 4 and FIG. 7. The TAL-ChAP-MS approach achieves high resolution and specificity by using the genomic targeting ability of the TALEN system for local epiproteome isolation and analysis. To alleviate genomic engineering for affinity enrichment of chromatin sections, a specific TAL-protein is designed with specificity for a target chromatin. This second-generation technology provides quantitative identification of specifically bound proteins and histone PTMs to a native chromatin region using label-free quantitative mass spectrometry.

To determine which of the identified proteins and posttranslational modifications of proteins associated with a target chromatin isolated from a cell are specifically or non-specifically associated with the target chromatin, a method of high-resolution mass spectrometry coupled with label-free proteomics was used. One with skill in the art will appreciate that label-free quantitative proteomics methods include the following fundamental steps: (i) sample preparation including protein extraction, reduction, alkylation, and digestion; (ii) sample separation by liquid chromatography (LC or LC/LC) and analysis by MS/MS; (iii) data analysis including peptide/protein identification, quantification, and statistical analysis. A method of the invention provides two cell samples, or lysates derived from two cell samples, comprising the target chromatin, wherein the target chromatin in one cell sample, but not both of the cell samples is tagged. With label-free quantitiative methods, each sample is separately prepared, then subjected to individual LC-MS/MS or LC/LC-MS/MS runs. As reviewed in Zhu et al., J Biomed Biotechnol 2010, and incorporated by reference herein, protein quantification is generally based on two categories of measurements. In the first are the measurements of ion intensity changes such as peptide peak areas or peak heights in chromatography. The second is based on spectral counting of identified proteins after MS/MS analysis. Peptide peak intensity or spectral count is measured for individual LC-MS/MS or LC/LC-MS/MS runs and changes in protein abundance are calculated via a direct comparison between different analyses.

In the present invention, the method of spectral counting is used to categorize whether proteins enriched with a section of chromatin are specific or contaminant. As such, determining the abundance of an identified protein in a tagged chromatin sample compared to the same protein in an untagged chromatin sample, may determine if the protein was specifically associated with the target chromatin of the invention. If a protein associated with a target chromatin is enriched in a tagged chromatin sample compared to the same protein in an untagged chromatin sample, then the protein is specifically associated with the target chromatin. If an identified protein is not enriched in a tagged chromatin sample compared to an untagged chromatin sample, then association of that protein with the target chromatin is not specific.

In the present invention, to measure enrichment of a protein, the normalized spectral abundance factor (NSAF) is calculated for each protein in each lane of an SDS-PAGE gel by dividing the number of spectral counts (normalized for the size of the protein) of a given protein by the sum of all normalized spectral counts of all proteins in the gel lane. The enrichment level for each protein is identified by calculating the fold enrichment (tagged chromatin/untagged chromatin) using the NSAF values.

As will be appreciated by a skilled artisan, the method of collecting a biological sample can and will vary depending upon the nature of the biological sample and the type of analysis to be performed. Any of a variety of methods generally known in the art may be utilized to collect a biological sample. Generally speaking, the method preferably maintains the integrity of the sample such that chromatin can be accurately detected and measured according to the invention.

As described in Section II above, two cell samples, or lysates derived from two cell samples may be subjected to mass-spectrometry coupled with label-free proteomics, one sample of which contains a tagged target chromatin of the invention. Typically, cells in two cell samples of the invention are from the same type of cells or they may be derived from the same type of cells or derived from the same biological sample. In some embodiments, cells may comprise a heterologous protein expressed in a cell of the invention. The heterologous protein expressed in a cell may be used for tagging a target chromatin as described in Section II(d). In some embodiments, cells in two cell samples of the invention are from the same type of cells. In other embodiments, cells in the first cell sample are derived from the same cell type as cells in the second cell sample.

Two cell samples of the invention may be from the same genus, species, variety or strain of cells or from the same biological sample. In a specific embodiment, two cell samples of the invention are Saccharomyces cerevisiae yeast cells or derivatives of Saccharomyces cerevisiae yeast cells. In exemplary embodiments, two cell samples of the invention are Saccharomyces cerevisiae W303a yeast cells or derivatives of Saccharomyces cerevisiae W303a yeast cells. In exemplary embodiments, two cell samples of the invention are derivatives of Saccharomyces cerevisiae W303a yeast cells, wherein-protein A tagged transcription activator-like (TAL) protein engineered to bind upstream of the GAL1 transcription start site is expressed in one of the cell samples of derived Saccharomyces cerevisiae W303a yeast cells.

The number of cells in a cell sample can and will vary depending on the type of cells, the abundance of a target chromatin in a cell, and the method of protein identification used, among other variables. For instance, if a cell of the invention is Saccharomyces cerevisiae, about 5×10¹⁰ to about 5×10¹², more preferably, about 1×10¹¹ to about 1×10¹² cells may be used in a cell sample. In some embodiments, about about 1×10¹¹ to about 1×10¹² Saccharomyces cerevisiae cells are used in a cell sample.

Two cell samples of the invention are typically grown identically. Identically grown cell samples minimizes potential structural or functional differences at a target chromatin present in both cell samples. As used herein, “grown identically” refers to cultured cell samples grown using similar culture condition, or cells from a tissue harvested using identical harvesting techniques, or biological samples collected, and optionally processed, via identical techniques.

(b) Chromatin

A method of the invention comprises identification of a protein and post-translational modification of a protein associated with a target chromatin. Generally, chromatin refers to the combination of nucleic acids and proteins in the nucleus of a eukaryotic cell. However, it is contemplated that the term “chromatin” may also refer to the combination of any nucleic acid sequence and proteins associated with the nucleic acid sequence in any cell.

Chromatin of the invention may be as described in Section I(b) above.

(c) Preparation of Cell Lysate

A target chromatin is isolated from a cell lysate derived from a cell sample, wherein a target chromatin is tagged in the cell sample. The method of isolating a target chromatin is also performed on a cell lysate derived from a cell sample, wherein a target chromatin is untagged in the cell sample. A skilled practitioner of the art will appreciate that structural and functional features of a target chromatin must be preserved during cell lysis and isolation of the target chromatin. The association of proteins with a target chromatin may be preserved during cell lysis and isolation of the target chromatin using methods known in the art for preserving a complex of proteins with a nucleic acid sequence. For instance, lysing of a cell and isolation of a target chromatin may be performed under refrigeration or using cryogenic methods and buffer conditions capable of preserving association of proteins and nucleic acid sequences. In addition, a complex of proteins with a nucleic acid may be preserved by crosslinking protein and nucleic acid complexes in a cell prior to lysing and isolating a chromatin. Crosslinking protein and nucleic acid complexes in a cell may also capture, or preserve, transient protein-protein and protein-nucleic acid interactions.

In some embodiments, a complex of proteins with a nucleic acid may be preserved by crosslinking protein and nucleic acid complexes in a chromatin prior to lysing a cell and isolating the chromatin. Crosslinking is the process of joining two or more molecules such as two proteins or a protein and a nucleic acid molecule, by a covalent bond. Molecules may be crosslinked by irradiation with ultraviolet light, or by using chemical crosslinking reagents. Chemical crosslinking reagents capable of crosslinking proteins and nucleic acids are known in the art and may include crosslinking reagents that target amines, sulfhydryls, carboxyls, carbonyls or hydroxyls; omobifunctional or heterobifunctional crosslinking reagent, variable spacer arm length or zero-length crosslinking reagents, cleavable or non-cleavable crosslinking reagents, and photoreactive crosslinking reagents. Non-limiting examples of crosslinking reagents that may be used to crosslink protein complexes and/or protein complexes and nucleic acids may include formaldehyde, glutaraldehyde, disuccinimidyl glutarate, disuccinimidyl suberate, a photoreactive amino acid such as photo-leucine or photo-methionine, and succinimidyl-diazirine. The degree of crosslinking can and will vary depending on the application of a method of the invention, and may be experimentally determined.

In a preferred embodiment, a complex of proteins with a nucleic acid in a chromatin of the invention may be preserved by crosslinking protein and nucleic acid complexes in a cell prior to lysing using formaldehyde. In an exemplary embodiment, a complex of proteins with a nucleic acid in a chromatin of the invention may be preserved by crosslinking protein and nucleic acid complexes in a cell prior to lysing using formaldehyde as described in the examples.

A skilled practitioner of the art will appreciate that protocols for lysing a cell can and will vary depending on the type of cell, the target chromatin of the invention, and the specific application of a method of the invention. Non limiting examples of methods that may be used to lyse a cell of the invention may include cell lysis using a detergent, an enzyme such as lysozyme, incubation in a hypotonic buffer which causes a cell to swell and burst, mechanical disruption such as liquid homogenization by forcing a cell through a narrow space, sonication, freeze/thaw, mortar and pestle, glass beads, and combinations thereof. In some embodiments, when a cell of the invention is a yeast cell, the cell may be cryogenically lysed under liquid nitrogen temperature with glass beads. In exemplary embodiments, when a cell of the invention is a yeast cell, the cell may be cryogenically lysed under liquid nitrogen temperature with glass beads as described in the examples.

Buffer conditions used during lysing and isolation of a chromatin of the invention can and will be altered to control stringent conditions during cell lysis and isolation to preserve association of proteins and nucleic acid sequences of a chromatin. “Stringent conditions” in the context of chromatin isolation are conditions capable of preserving specific association of proteins and nucleic acids of a chromatin, but minimizing non-specific association of proteins and nucleic acids. Stringent conditions can and will vary depending on the application of a method of the invention, the target chromatin of the invention, the nucleic acid sequence in a target chromatin, the proteins or protein complexes associated with a target chromatin of the invention, whether or not proteins, protein complexes and nucleic acid sequences are crosslinked, and the conditions used for crosslinking proteins, protein complexes and nucleic acid sequences of a target chromatin. For instance, more stringent buffer conditions may be used in a method of the invention wherein proteins, protein-protein complexes, and protein-nucleic acid complexes are crosslinked compared to a method of the invention wherein proteins, protein-protein complexes, and protein-nucleic acid complexes are not crosslinked. As such, stringent buffer conditions used during cell lysis and isolation of a nucleic acid sequence of the invention may be experimentally determined for each application wherein a method of the invention is used. Buffer conditions that may alter stringent conditions during cell lysis and isolation may include pH and salt concentration. In preferred embodiments, proteins, protein-protein complexes, and protein-nucleic acid complexes of a target chromatin of the invention are crosslinked, and stringent buffer conditions are used during lysis and isolation of a chromatin of the invention. In exemplary embodiments, proteins, protein-protein complexes, and protein-nucleic acid complexes of a target chromatin of the invention are crosslinked, and stringent buffer conditions are used during lysis and isolation of a chromatin of the invention and are as described in the examples.

(d) Chromatin Isolation

According to the invention, the method of isolating a target chromatin is performed on cell lysates derived from cell samples, wherein one sample comprises a target chromatin that is tagged in the cell sample and one sample comprises a target chromatin that is untagged in the cell sample. As described in Sections II(a) and II(c) above, a cell lysate comprises a lysate of a cell sample, wherein a target chromatin is tagged in one of the lysates, or one of the cell samples. A cell lysate also comprises a lysate of a cell sample, wherein a target chromatin is not tagged in one of the lysates, or one of the cell samples.

A target chromatin may be isolated from a mixture of chromatins or chromatin fragments in a cell lysate as described in this section. As used herein, a target nucleic acid sequence is said to be “isolated” or “purified” when it is substantially free of proteins not associated with the target chromatin, nucleic acid sequences other than the nucleic acid sequences associated with the target chromatin, and other cell debris and cell contents resulting from extraction and preparation of the target chromatin from a cell. A target chromatin of the present invention may be purified to homogeneity or other degrees of purity. In general, the level of purity of an isolated target chromatin can and will vary depending on the cell type, the specific chromatin to be isolated, and the intended use of a target chromatin of the invention. The level of purity of an isolated target chromatin may be determined using methods known in the art. For instance, the level of purity of an isolated target chromatin may be determined by determining the level of purity of a nucleic acid sequence associated with a target chromatin, by determining the level of purity of a protein associated with a target chromatin, or by determining the level of enrichment of a target chromatin, compared to a non-target chromatin in a cell. In preferred embodiments, the level of purity of an isolated target chromatin is determined by determining the level of enrichment of a target chromatin, compared to a non-target chromatin in a cell. Determining the level of enrichment of a target chromatin, compared to a non-target chromatin in a cell may be as described in this section below.

A target chromatin of the invention may be isolated using methods known in the art, such as electrophoresis, molecular, immunological and chromatographic techniques, ion exchange, hydrophobic, affinity, and reverse-phase HPLC chromatography, size exclusion chromatography, precipitation, dialysis, chromatofocusing, ultrafiltration and diafiltration techniques, and combinations thereof. For general guidance in suitable purification techniques, see Scopes, R., Protein Purification, Springer-Vertag, NY (1982).

In general, a method of the invention comprises isolating a target chromatin by affinity purification, or affinity purification in combination with other methods of isolating chromatin described above. In a preferred embodiment, a method of the invention comprises isolating a target chromatin by affinity purification. Non-limiting examples of affinity purification techniques that may be used to isolate a target chromatin of the invention may include affinity chromatography, immunoaffinity chromatography, size exclusion chromatography, and combinations thereof. See, for example, Roe (ed), Protein Purification Techniques: A Practical Approach, Oxford University Press, 2nd edition, 2001.

In essence, affinity purification of a target chromatin may comprise tagging a target chromatin by contacting the target chromatin of the invention with a tag capable of specifically recognizing and binding one or more portions of a target chromatin. As described in Section II, a target chromatin from one cell sample, or lysate derived from the cell sample of the invention, but not both of the cell samples, is tagged.

A tag may be capable of specifically recognizing and binding 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 components of a target chromatin. In preferred embodiments, a tag is capable of specifically recognizing and binding one component of a target chromatin.

A tag may be capable of specifically recognizing and binding a component in a target chromatin. A component in a target chromatin may be a nucleic acid sequence in a nucleic acid associated with a target chromatin, a protein associated with a target chromatin, or a chromatin structural or functional feature in a target chromatin. In some embodiments, a tag is capable of specifically recognizing and binding a protein associated with a target chromatin. In other embodiments, a tag is capable of specifically recognizing and binding a chromatin structural or functional feature in a target chromatin. In preferred embodiments, a tag is capable of specifically recognizing and binding a nucleic acid sequence associated with a target chromatin.

A nucleic acid sequence associated with a target chromatin that may be specifically recognized and bound by a tag of the invention may be a nucleic acid sequence normally found in a chromatin of a cell of the invention. Individuals of ordinary skill in the art will recognize that a tag introduced into a cell to facilitate tagging a target chromatin of the invention cannot and will not disrupt a target chromatin, or a structural or functional feature of a target chromatin. Methods of designing a tag capable of binding the chromatin component that do not disrupt a chromatin of the invention may depend on the particular application of a method of the invention, and may be determined experimentally. For instance, if an application of a method of the invention comprises promoter function, a tag may be designed to bind anywhere adjacent to the promoter, but without disrupting the promoter.

In some embodiments, a tag of the invention is a nucleic acid tag capable of binding a nucleic acid sequence component of a chromatin, wherein the nucleic acid sequence component of the chromatin is introduced into a cell of the invention. In some embodiments, a tag of the invention is a nucleic acid tag capable of binding a nucleic acid sequence component of a chromatin, wherein the nucleic acid sequence component of the chromatin is normally present in a cell of the invention. Non-limiting examples of nucleic acid tags capable of binding a nucleic acid sequence component of a chromatin include antisense RNA or DNA nucleic acid tags, and tags comprising modified nucleic acids and nucleic acid mimics such as peptide nucleic acids, locked nucleic acids, phosphorodiamidate morpholino oligomers (PMO). In some embodiments, a tag of the invention is a nucleic acid tag comprising locked nucleotides. For instance, a nucleic acid tag comprising locked nucleotides may be as described in US20110262908 or US20120040857, and a peptide nucleic acid tag may be as described in Boffa et al. 1995 PNAS 92:1901-1905, the disclosures of all of which are incorporated herein in their entirety.

In specific embodiments, a tag of the invention is a protein tag capable of binding a nucleic acid sequence component of a chromatin, wherein the nucleic acid sequence component of the chromatin is a nucleic acid sequence normally found in a chromatin of a cell of the invention. Non limiting examples of a protein tag capable of binding a nucleic acid sequence normally found in a chromatin of a cell may be a nucleic acid binding protein such as protein A, the Lac repressor, a zinc finger protein, a transcription activator protein capable of binding a nucleic acid, or a transcription activator-like (TAL) protein. In one embodiment, a tag of the invention is a transcription activator protein capable of binding a nucleic acid sequence normally found in a chromatin of a cell of the invention. In another embodiment, a tag of the invention is a zinc finger protein capable of binding a nucleic acid sequence normally found in a chromatin of a cell of the invention. In an exemplary embodiment, a tag of the invention is transcription activator-like (TAL) protein capable of binding a nucleic acid sequence normally found in a chromatin of a cell of the invention.

A nucleic acid binding protein tag of the invention may be a wild type nucleic acid binding protein capable of binding a nucleic acid sequence normally found in a target chromatin. Alternatively, a nucleic acid binding protein tag of the invention may be engineered to specifically recognize a nucleic acid sequence component normally found in a target chromatin of the invention. Individuals of ordinary skill in the art will recognize that nucleic acid binding proteins such as zinc finger proteins, transcription activator proteins, and transcription activator-like (TAL) proteins may be engineered to have novel nucleic acid binding specificity compared to naturally-occurring forms of the proteins. See, for example, U.S. Pat. Nos. 6,453,242 and 6,534,261, and U.S. Pate. Appl. Nos 20110239315, 20120110685, and 20120270273, the disclosures of which are incorporated by reference herein in their entireties. In some embodiments, a nucleic acid binding protein tag of the invention is a wild type nucleic acid binding protein capable of binding a nucleic acid sequence normally found in a target chromatin. In other embodiments, a nucleic acid binding protein tag of the invention is a nucleic acid binding protein engineered to specifically recognize a nucleic acid sequence component of a target chromatin of the invention. In a preferred embodiment, a nucleic acid binding protein tag of the invention is a zinc finger protein engineered to specifically recognize a nucleic acid sequence component of a target chromatin of the invention. In an exemplary embodiment, a nucleic acid binding protein tag of the invention is a TAL protein engineered to specifically recognize a nucleic acid sequence component of a target chromatin of the invention.

A tag of the invention may further comprise one or more affinity handles. As used herein, the term “affinity handle” may refer to any handle that may be bound by a substrate for affinity purification, as described below. A tag may comprise one or more than one affinity handle. The inclusion of more than one affinity handle in a tag of the invention may significantly increase the efficiency of affinity purification for a low copy number chromatin target. As such, a tag may further comprise 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more affinity handles. In a preferred embodiment, a tag of the invention comprises one affinity handle.

Affinity handles may include any affinity handle for which a cognate binding agent is readily available. An affinity handle may be an aptamer, an antibody, an antibody fragment, a double-stranded DNA sequence, modified nucleic acids and nucleic acid mimics such as peptide nucleic acids, locked nucleic acids, phosphorodiamidate morpholino oligomers (PMO), a ligand, a ligand fragment, a receptor, a receptor fragment, a polypeptide, a peptide, a coenzyme, a coregulator, an allosteric molecule, non-immunoglobulin scaffolds such as Affibodies, Anticalins, designed Ankyrin repeat proteins and others, an ion, or a small molecule for which a cognate binding agent is readily available. The term “aptamer” refers to a polypeptide or a polynucleotide capable of binding to a target molecule at a specific region. It is generally accepted that an aptamer, which is specific in its binding to any polypeptide, may be synthesized and/or identified by in vitro evolution methods. Non limiting examples of handles that may be suitable for isolating a chromatin may include biotin or a biotin analogue such as desthiobiotin, digoxigenin, dinitrophenol or fluorescein, antigenic polypeptides such as protein A, or peptide ‘tags’ such as polyhistidine, FLAG, HA and Myc tags. In preferred embodiments, a tag of the invention comprises an antigenic polypeptide as an affinity handle. In other preferred embodiments, a tag of the invention comprises protein A or derivatives thereof as an affinity handle. In a specific embodiment, a tag of the invention comprises protein A-tagged TAL protein. The TAL protein can be engineered to specifically recognize a nucleic acid sequence component of a target chromatin of the invention. As such, TAL may be used as an affinity purification tag for purifying a target chromatin. Protein A comprises an affinity handle capable of binding IgG. In exemplary embodiments, a tag of the invention comprises the protein A tagged TAL protein engineered to bind upstream of the GAL1 transcription start site.

A target chromatin may be contacted with a tag at any time during a method of the invention leading to isolation of target chromatin. For instance, a target chromatin may be contacted with a protein tag during cell culture by expressing the protein tag in a cell of the invention. Alternatively, a target chromatin may be contacted with a tag after cell culture but before cell lysis, after cell lysis, or after fragmentation of chromatin to generate chromatin fragments comprising a target chromatin. In such embodiments, a tag may be added to the cell culture or cell lysate as a recombinant protein. The recombinant protein may be expressed, isolated and purified via methods standard in the art for protein purification.

In some embodiments, a target chromatin is contacted with a tag after cell culture but before cell lysis. As such, a tag may be introduced into a cell before cell lysis. Methods of introducing a tag into a cell of the invention can and will vary depending on the type of cell, the tag, and the application of a method of the invention. For instance, a nucleic acid tag may be electroporated into a cell after culture. In other embodiments, a target chromatin is contacted with a tag after cell lysis. In such an embodiment, a tag may be added to the cell lysate as a recombinant protein. In yet other embodiments, a target chromatin is contacted with a tag after cell lysis and chromatin fragmentation. In certain embodiments, a target chromatin is contacted with a tag during cell culture by expressing the tag in a cell of the invention during cell culture. In exemplary embodiments, a target chromatin is contacted with a protein A tagged TAL protein during cell culture by expressing the protein A tagged TAL protein in a cell of the invention during cell culture.

A target chromatin contacted and bound by a tag as described above may be isolated using an affinity handle of the tag. The term “isolated”, may be used herein to describe a purified preparation of a target chromatin that is enriched for the target chromatin, but wherein the target chromatin is not necessarily in a pure form. That is, an isolated target chromatin is not necessarily 100% pure, but may be about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90% pure. An isolated target chromatin may be enriched for the target chromatin, relative to a chromatin in the lysed preparation that was not contacted by a tag of the invention. An isolated target chromatin may be enriched by 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 fold relative to a chromatin that is not contacted by a tag of the invention. In some embodiments, an isolated target chromatin is enriched by 2, 3, 4, or 5 fold relative to a chromatin that was not contacted by a tag of the invention. In other embodiments, an isolated target chromatin is enriched by 5, 6, 7, 8, 9, or 10 fold relative to a chromatin that was not contacted by a tag of the invention. In an exemplary embodiment, an isolated target chromatin is enriched 4, 5, or 6 fold relative to a chromatin that was not contacted by a tag of the invention.

A target chromatin contacted and bound by a tag as described above may be isolated using any affinity purification method known in the art. In short, a tagged target chromatin is bound to a substrate capable of binding the affinity handle. The substrate comprising a bound target chromatin may then be washed to remove non-target chromatin and other cell debris, and the target chromatin may be released from substrate. Methods of affinity purification of material comprising an affinity handle are known in the art and may include binding the affinity handle to a substrate capable of binding the affinity handle. The substrate may be a gel matrix such as gel beads, the surface of a container, or a chip. The tagged target chromatin bound to the substrate may then be purified. Methods of purifying tagged molecules are known in the art and will vary depending on the target molecule, the tag, and the substrate. For instance, if the tag is a TAL-protein A tag bound to a site in a target chromatin, the target chromatin may be bound to a magnetic bead substrate comprising IgG, and purified using a magnet.

(e) Protein Extraction, Identification, and Determination of Labeling

Proteins and peptides associated with an isolated target chromatin are extracted from the isolated target chromatin. Methods of extracting proteins from chromatin are generally known in the art of protein biochemistry. Generally, any extraction protocol suitable for isolating proteins and known to those of skill in the art may be used. Extracted proteins may also be further purified before protein identification. For instance, protein extracts may be further purified by differential precipitation, differential solubilization, ultracentrifugation, using chromatographic methods such as size exclusion chromatography, hydrophobic interaction chromatography, ion exchange chromatography, affinity chromatography, metal binding, immunoaffinity chromatography, HPLC, or gel electrophoriesis such as SDS-PAGE and QPNC-PAGE. In a preferred embodiment, extracted proteins are further purified using SDS-PAGE.

Extracted and purified intact proteins and post-translational modification of proteins may then be identified. Alternatively, extracted and purified intact proteins may be further digested, and the resulting peptide fragments are identified. In some embodiments, intact extracted proteins are identified. In preferred embodiments, extracted proteins are further digested, and the resulting peptide fragments are identified. For instance, protein extracts may be fragmented by enzymatically digesting the proteins using a protease such as trypsin. In exemplary embodiments, extracted proteins are further digested as described in the examples.

Methods of identifying proteins or protein fragments are known in the art and may include mass spectrometry (MS) analysis, or a combination of mass spectrometry with a chromatographic technique. Non limiting examples of mass spectrometer techniques may include tandem mass spectrometry (MS/MS), matrix-assisted laser desorption/ionization source with a time-of-flight mass analyzer (MALDI-TOF), inductively coupled plasma-mass spectrometry (ICP-MS), accelerator mass spectrometry (AMS), thermal ionization-mass spectrometry (TIMS), isotope ratio mass spectrometry (IRMS), and spark source mass spectrometry (SSMS). Chromatographic techniques that may be used with MS may include gas chromatography, liquid chromatography, and ion mobility spectrometry. In a preferred embodiment, proteins may be identified using tandem mass spectrometry in combination with liquid chromatography (LC-MS/MS). In another preferred embodiment, post-translational modification of proteins may be identified using tandem mass spectrometry in combination with liquid chromatography (LC-MS/MS).

In the present invention, the method of label-free proteomics is used to categorize whether proteins enriched with a section of chromatin are specific or contaminant. Label-free methods of quantifying proteins or protein fragments are known in the art. In label-free quantitative proteomics, each sample is separately prepared, then subjected to individual methods of identifying proteins or protein fragments which may include LC-MS/MS or LC/LC-MS/MS. According to the invention, one sample comprises a target chromatin that is tagged in the cell sample and one sample comprises a target chromatin that is untagged in the cell sample. Label-free protein quantification is generally based on two categories of measurement. In the first are the measurements of ion intensity changes such as peptide peak areas or peak heights in chromatography. The second is based on the spectral counting of identified proteins after MS/MS analysis. Peptide peak intensity or spectral count is measured for individual LC-MS/MS or LC/LC-MS/MS runs and changes in protein abundance are calculated via a direct comparison between different analyses. In a preferred embodiment, the proteins identified using mass spectrometry are quantified and identified as enriched in the sample containing the tagged target chromatin compared to the sample containing the untagged target chromatin using label-free proteomics. In an exemplary embodiment, the proteins identified using mass spectrometry are quantified and identified as enriched in the sample containing the tagged target chromatin compared to the sample containing the untagged target chromatin using spectral counting.

The method of protein quantification by spectral count is known in the art and is reviewed in Zhu et al., J Biomed Biotechnol 2010, which is incorporated by reference herein. In spectral counting, relative protein quantification is achieved by comparing the number of identified MS/MS spectra from a protein of one sample to the same protein in the other sample. In the present invention, one sample comprises a target chromatin that is tagged and another sample comprises a target chromatin that is untagged. Protein quantification in spectral counting utilizes the fact that an increase in protein abundance typically results in an increase in the number of its proteolytic peptides, and vice versa. This increased number of (tryptic) digests then usually results in an increase in protein sequence coverage, the number of identified unique peptides, and the number of identified total MS/MS spectra (spectral count) for each protein.

As such, determining the abundance of an identified protein in a tagged chromatin sample compared to the same protein in an untagged chromatin sample, may determine if the protein was specifically associated with a target chromatin of the invention. If an identified protein associated with a target chromatin is in enriched in a tagged chromatin sample compared to the same protein in an untagged chromatin sample, then the protein was specifically associated with a target chromatin of the invention. If an identified protein is not enriched in a tagged chromatin sample compared to an untagged chromatin sample, then the protein is non-specifically associated with a target chromatin of the invention.

A skilled artisan in spectral counting will appreciate that normalization and statistical analysis of spectral counting datasets are necessary for accurate and reliable detection of protein changes. Since large proteins tend to contribute more peptide/spectra than small ones, a normalized spectral abundance factor (NSAF) is defined to account for the effect of protein length on spectral count. NSAF is calculated as the number of spectral counts (SpC) identifying a protein, divided by the protein's length (L), divided by the sum of SpC/L for all proteins in the experiment. NSAF allows the comparison of abundance of individual proteins in multiple independent samples and has been applied to quantify the expression changes in various complexes.

In the present invention, to measure enrichment of a protein, the normalized spectral abundance factor (NSAF) is calculated for each protein in each lane of an SDS-PAGE gel by dividing the number of spectral counts (normalized for the size of the protein) of a given protein by the sum of all normalized spectral counts of all proteins in the gel lane. The enrichment level for each protein is identified by calculating the fold enrichment (tagged chromatin/untagged chromatin) using the NSAF values. In an exemplary embodiment, proteins enriched in a sample containing a tagged target chromatin compared to a sample containing an untagged target chromatin are enriched by at least about 2 fold. In other embodiments, proteins enriched in a sample containing a tagged target chromatin compared to a sample containing the untagged target chromatin are enriched by at least about 1.5 fold. In other embodiments, proteins enriched in a sample containing a tagged target chromatin compared to a sample containing an untagged target chromatin are enriched by at least about 3 fold, about 4 fold, about 5 fold, about 6 fold, about 7 fold, about 8 fold, about 9 fold, about 10 fold, about 11 fold, about 12 fold, about 13 fold, about 14 fold, about 15 fold, about 16 fold, about 17 fold, about 18 fold, about 19 fold or about 20 fold. As such, a protein enriched by at least about 2 fold in a tagged chromatin sample compared to an untagged chromatin sample, is specifically associated with the chromatin. For instance, a baseline for non-specifically associated proteins may be proteins enriched by less than about 1.5 fold in a tagged chromatin sample compared to an untagged chromatin sample, wherein one or more proteins are not associated with chromatin. Non-limiting examples of proteins not associated with a chromatin may include enzymes required for metabolism, receptors, and ribosomal proteins. In preferred embodiments, proteins not associated with a chromatin are ribosomal proteins, and a baseline for non-specifically associated proteins is an enrichment less than about 1.5 fold in a tagged chromatin sampled compared to an untagged chromatin sample. In an exemplary embodiment, proteins or protein fragments enriched by at least 15 fold in a tagged chromatin sample compared to an untagged chromatin sample are specifically associated with a target chromatin.

In preferred embodiments, a target chromatin is tagged in one cell sample and a target chromatin is untagged in a second cell sample, and MS analysis is used to identify proteins or protein fragments isolated during affinity purification of each sample, and label-free proteomics is used to determine if a protein or a protein fragment is specifically or non-specifically associated with the target chromatin. Methods of deriving MS data to identify proteins or protein fragments are known in the art, and may include using known computational techniques to distill MS data such as Mascot Distiller, Rosetta Elucidator, and MaxQuant. In some embodiments, MS data is derived using Rosetta Elucidator. In other embodiments, MS data is derived using MaxQuant. In preferred embodiments, MS data is derived using Mascot Distiller.

III. Method of CRISPR-ChAP-MS

In yet another aspect, the invention provides a method of isolating and identifying proteins specifically associated with a target chromatin using the Cas9 and guide RNA (gRNA) components of the CRISPR system as described in Example 6 and FIG. 9. The CRISPR-ChAP-MS approach provides a new tool to study epigenetic regulation. Identification of proteins and histone PTMs at 1 kb resolution does not depend on a priori knowledge of a protein/PTM target, which distinguishes this method from traditional ChIP. This third-generation technology provides quantitative identification of specifically bound proteins and histone PTMs with an enhanced ability to isolate targeted chromatin only requiring site-directed mutagenesis to alter the gRNA for genomic targeting.

The present disclosure provides a method of identifying proteins including proteins comprising posttranslational modifications specifically associated with a target chromatin in a cell. The method comprises providing a first cell sample comprising nucleic acid binding proteins and the target chromatin, wherein the target chromatin is tagged by contacting the target chromatin with a tag capable of specifically recognizing and binding one or more portions of the target chromatin and wherein the tag comprises an affinity handle, and a second cell sample comprising nucleic acid binding proteins and the target chromatin, wherein the target chromatin is not tagged by contacting the target chromatin with a non-functional tag that is not capable of specifically recognizing and binding one or more portions of the target chromatin and wherein the non-functional tag comprises an affinity handle. Affinity handle from each sample is isolated wherein affinity handle isolated from the first cell sample consists of affinity handle bound to tagged target chromatin bound to specifically associated nucleic acid binding proteins and affinity handle bound to non-specifically associated nucleic acid binding proteins and affinity handle isolated from the second cell sample consists of affinity handle bound to non-specifically associated nucleic acid binding proteins, wherein isolating the affinity handle enriches for the tagged target chromatin. Bound protein in each cell sample is identified. Then, the amount of each bound protein in each cell sample is determined, wherein bound proteins that are enriched in the first cell sample as compared to the second cell sample are specifically associated with the tagged chromatin in the first cell sample.

The key to success with the CRISPR-ChAP-MS is the enhanced ability to isolate targeted chromatin. Further, CRISPR-ChAP-MS only requires site-directed mutagenesis to alter the gRNA for genomic targeting, which provides a more cost effective approach that can easily be multiplexed to target additional sites. The chromatin enrichment methodology described herein is quantitative mass spectrometry used to determine proteins/PTMs specific to the isolated chromatin. The mass spectrometric approach used in the CRISPR-ChAP-MS approach is label-free. With label-free quantitative methods, each sample is separately prepared, then subjected to individual LC-MS/MS or LC/LC-MS/MS runs. The method of spectral counting is used to categorize whether proteins enriched with a section of chromatin are specific or contaminant. As such, determining the abundance of an identified protein in a tagged chromatin sample compared to the same protein in an untagged chromatin sample, may determine if the protein was specifically associated with the target chromatin of the invention. If a protein associated with a target chromatin is enriched in a tagged chromatin sample compared to the same protein in an untagged chromatin sample, then the protein is specifically associated with the target chromatin. If an identified protein is not enriched in a tagged chromatin sample compared to an untagged chromatin sample, then association of that protein with the target chromatin is not specific.

As will be appreciated by a skilled artisan, the method of collecting a biological sample can and will vary depending upon the nature of the biological sample and the type of analysis to be performed. Any of a variety of methods generally known in the art may be utilized to collect a biological sample. Generally speaking, the method preferably maintains the integrity of the sample such that chromatin can be accurately detected and measured according to the invention.

As described in Section III above, two cell samples, or lysates derived from two cell samples may be subjected to mass-spectrometry coupled with label-free proteomics, one sample of which contains a tagged target chromatin of the invention. Typically, cells in a first cell sample and a second cell sample of the invention are from the same type of cells or may be derived from the same type of cells or derived from the same biological sample. In some embodiments, cells may comprise a heterologous nucleic acid expressed in a cell of the invention, and may also comprise a heterologous protein expressed in a cell of the invention. The heterologous nucleic acid and protein expressed in a cell may be used for tagging a chromatin of the invention as described in Section III(c).

In an exemplary embodiment, about 1×10¹⁰ Saccharomyces cerevisiae cells are used.

A first cell sample and a second cell sample of the invention are typically grown identically. Identically grown cell samples minimizes potential structural or functional differences at a target chromatin present in both cell samples. As used herein, “grown identically” refers to cultured cell samples grown using similar culture condition, or cells from a tissue harvested using identical harvesting techniques, or biological samples collected, and optionally processed, via identical techniques.

(b) Chromatin

According to the invention, a first cell sample and a second cell sample of the invention comprise nucleic acid binding proteins and a target chromatin. As used herein, “nucleic acid binding proteins” refers to proteins that bind nucleic acid. Nucleic acid binding proteins are proteins that are composed of nucleic acid-binding domains and thus have specific or general specificity for either single or double stranded nucleic acid. A nucleic acid binding protein may bind nucleic acid specifically or nonspecifically. Non-specific association of nucleic acid binding proteins with chromatin makes it challenging to identify proteins that are specifically bound to chromatin. The methodology of the present disclosure overcomes this challenge by reducing the amount of non-specific proteins bound to chromatin and enriching for proteins specifically bound to chromatin.

As used herein, “chromatin” refers to a target nucleic acid sequence that may be isolated from a cell. Generally, chromatin refers to the combination of nucleic acids and proteins in the nucleus of a eukaryotic cell. However, it is contemplated that the term “chromatin” may also refer to the combination of a nucleic acid sequence and proteins associated with the nucleic acid sequence in a cell.

A chromatin of the invention may comprise single stranded nucleic acid, double stranded nucleic acid, or a combination thereof. In some embodiments, a chromatin comprises single stranded nucleic acid. In other embodiments, a chromatin comprises a combination of single stranded and double stranded nucleic acids. In yet other embodiments, a chromatin comprises double stranded nucleic acid.

A chromatin of the invention may comprise a ribonucleic acid (RNA), a deoxyribonucleic acid (DNA), or a combination of RNA and DNA. In some embodiments, a chromatin of the invention comprises a combination of a RNA sequence and proteins associated with the RNA sequence in a cell. Non-limiting examples of RNA sequences may include mRNA, and non-coding RNA such as tRNA, rRNA, snoRNAs, microRNAs, siRNAs, piRNAs and the long noncoding RNA (IncRNA). In preferred embodiments, a chromatin of the invention comprises a combination of a DNA sequence and proteins associated with the DNA sequence in a cell. In other preferred embodiments, a chromatin of the invention comprises a combination of RNA and DNA sequences, and proteins associated with the RNA and DNA sequence in a cell. Non limiting examples of chromatin that may comprise a combination of RNA and DNA may include genomic DNA undergoing transcription, or genomic DNA comprising non-coding RNA such as IncRNA.

A chromatin of the invention may be genomic chromatin such as, chromatin from a chromosome of a cell, or chromatin from an organelle in the cell. Alternatively, a chromatin may be chromatin from an extrachromosomal nucleic acid sequence. In some embodiments, a chromatin of the invention is chromatin from an organelle in the cell. Non-limiting examples of a chromatin from an organelle may include mitochondrial nucleic acid sequence in plant and animal cells, and a chloroplast nucleic acid sequence in plant cells. In some embodiments, a nucleic acid sequence of the invention is a mitochondrial nucleic acid sequence. In other embodiments, a nucleic acid sequence of the invention is a chloroplast nucleic acid sequence.

In some embodiments, a chromatin of the invention is chromatin from an extrachromosomal nucleic acid sequence. The term “extrachromosomal,” as used herein, refers to any nucleic acid sequence not contained within the cell's genomic nucleic acid sequence. An extrachromosomal nucleic acid sequence may comprise some sequences that are identical or similar to genomic sequences in the cell, however, an extrachromosomal nucleic acid sequence as used herein does not integrate with genomic sequences of the cell. Non-limiting examples of an extrachromosomal nucleic acid sequence may include a plasmid, a virus, a cosmid, a phasmid, and a plasmid.

In some preferred embodiments, a chromatin of the invention is genomic chromatin. In exemplary embodiments, a chromatin of the invention is genomic chromatin of a eukaryotic cell. A eukaryotic cell of the invention may be as described in Section III(a) above.

Primary functions of genomic chromatin of a eukaryotic cell may be DNA packaging into a smaller volume to fit in the cell, strengthening of the DNA to allow mitosis, prevent DNA damage, and to control gene expression and DNA replication. As described above, genomic chromatin of a eukaryotic cell may comprise DNA sequences and a plurality of DNA-binding proteins as well as certain RNA sequences, assembled into higher order structural or functional regions. As used herein, a “structural or functional feature of a chromatin”, refers to a chromatin feature characterized by, or encoding, a function such as a regulatory function of a promoter, terminator, translation initiation, enhancer, etc., or a structural feature such as heterochromatin, euchromatin, a nucleosome, a telomere, or a centromere. A physical feature of a nucleic acid sequence may comprise a functional role and vice versa. As described below, a chromatin of the invention may be a chromatin fragment, and as such may comprise a fragment of a physical or functional feature of a chromatin, or no physical or functional features or known physical or functional features.

The primary protein components of genomic eukaryotic chromatin are histones that compact the DNA into a nucleosome. The nucleosome comprises an octet of histone proteins around which is wound a stretch of double stranded DNA sequence of about 150 to about 250 bp in length. Histones H2A, H2B, H3 and H4 are part of the nucleosome while histone H1 may act to link adjacent nucleosomes together into a higher order structure. Histones are subject to post translational modification which may affect their function in regulating chromatin function. Such modifications may include methylation, citrullination, acetylation, phosphorylation, SUMOylation, ubiquitination, and ADP-ribosylation.

Many further polypeptides and protein complexes interact with the nucleosome and the histones to regulate chromatin function. A “polypeptide complex” as used herein, is intended to describe proteins and polypeptides that assemble together to form a unitary association of factors. The members of a polypeptide complex may interact with each other via non-covalent or covalent bonds. Typically members of a polypeptide complex will cooperate to enable binding either to a nucleic acid sequence or to polypeptides and proteins already associated with or bound to a nucleic acid sequence in chromatin. Chromatin associated polypeptide complexes may comprise a plurality of proteins and/or polypeptides which each serve to interact with other polypeptides that may be permanently associated with the complex or which may associate transiently, dependent upon cellular conditions and position within the cell cycle. Hence, particular polypeptide complexes may vary in their constituent members at different stages of development, in response to varying physiological conditions or as a factor of the cell cycle. By way of example, in animals, polypeptide complexes with known chromatin remodelling activities include Polycomb group gene silencing complexes as well as Trithorax group gene activating complexes.

A chromatin of the invention may be an intact and complete chromatin from the cell, or may be a fragment of a chromatin in a cell. In some embodiments, a chromatin of the invention is an intact chromatin isolated from a cell. For instance, a chromatin of the invention may be a plasmid, a cosmid, or a phage chromatin or a complete organellar chromatin. In preferred embodiments, a chromatin of the invention is a fragment of a chromatin from a cell. In exemplary embodiments, a chromatin of the invention is a fragment of a genomic chromatin from a cell.

When a chromatin of the invention is a fragment of a chromatin in a cell, any method of fragmenting a chromatin known in the art may be used. Such methods may include physical methods of fragmenting a chromatin, or enzymatic digestion of a nucleic acid sequence of a chromatin. In some embodiments, a fragment of a chromatin may be generated using enzymatic digestion of a nucleic acid sequence in chromatin. Non-limiting examples of enzymatic digestion may include random or sequence specific enzymatic digestion using restriction enzymes, nucleases, combinations of restriction enzymes and nucleases, or combinations of nicking and other nucleases such as NEBNext™ fragmentase, which comprises a nicking enzyme that randomly generates nicks in double stranded DNA and another enzyme that cuts the strand opposite to the generated nicks.

In other embodiments, a fragment of a chromatin may be generated using a physical method of fragmenting a chromatin. Non-limiting examples of physical fragmenting methods that may be used to fragment a chromatin of the invention may include nebulization, sonication, and hydrodynamic shearing. In some embodiments, a fragment of a chromatin may be generated using nebulization. In other embodiments, a fragment of a chromatin may be generated using hydrodynamic shearing. In preferred embodiments, a fragment of a chromatin may be generated using sonication. During sonication, a sample comprising chromatin is subjected to ultrasonic waves, whose vibrations produce gaseous cavitations in the liquid that shear or break high molecular weight molecules such as chromatin through resonance vibration. Sonication methods that may be used to generate a chromatin of the invention are known in the art

In another preferred embodiment, a chromatin of the invention may comprise a nucleic acid sequence fragment of about 1200, 1210, 1220, 1230, 1240, 1250, 1260, 1270, 1280, 1290, or about 1300 bases long.

As described in this section above, a chromatin of the invention may comprise one or more nucleosomes. As such, a chromatin fragment of the invention may comprise 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or about 20 nucleosomes. In some embodiments, a chromatin fragment of the invention may comprise about 1, 2, 3, 4, or about 5 nucleosomes. In other embodiments, a chromatin fragment of the invention may comprise about 5, 6, 7, 8, 9, or about 10 nucleosomes. In yet other embodiments, a chromatin fragment of the invention may comprise about 10, 11, 12, 13, 14, or about 15 nucleosomes. In other embodiments, a chromatin fragment of the invention may comprise about 15, 16, 17, 18, 19, or about 20 nucleosomes. In preferred embodiments, a chromatin fragment of the invention may comprise about 4 nucleosomes. In other preferred embodiments, a chromatin fragment of the invention may comprise about 5 nucleosomes.

In some embodiments, a target chromatin fragment of the invention comprises a structural feature of chromatin. In other embodiments, a target chromatin fragment of the invention comprises no physical or functional features or known physical or functional features. In yet other embodiments, a target chromatin fragment of the invention comprises a functional feature of chromatin. In exemplary embodiments, a target chromatin is a promoter.

(c) Tagging the Target Chromatin

According to the invention, a target chromatin from a first cell sample is tagged and a target chromatin from a second cell sample is not tagged. In essence, tagging a target chromatin may comprise contacting the target chromatin of the invention with a tag capable of specifically recognizing and binding one or more portions of a target chromatin. As used herein, “specifically recognizing” refers to a binding reaction between two separate molecules that is at least two times the background and more typically more than 10 to 100 times the background molecular associations under physiological conditions. A tag may be capable of specifically recognizing and binding 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 components of a target chromatin. In preferred embodiments, a tag is capable of specifically recognizing and binding one component of a target chromatin. Alternatively, not tagging a target chromatin may comprise contacting the target chromatin with a non-functional tag that is not capable of specifically recognizing and binding one or more portions of the target chromatin. Specifically, the non-functional tag lacks a component of the tag that is essential for specifically recognizing and thus tagging the target chromatin.

A tag may be capable of specifically recognizing and binding a component in a target chromatin. A component in a target chromatin may be a nucleic acid sequence in a nucleic acid associated with a target chromatin, a protein associated with a target chromatin, or a chromatin structural or functional feature in a target chromatin. A nucleic acid sequence associated with a target chromatin that may be specifically recognized and bound by a tag of the invention may be a nucleic acid sequence normally found in a chromatin of a cell of the invention.

Individuals of ordinary skill in the art will recognize that an exogenous component introduced into a cell to facilitate tagging a target chromatin of the invention cannot and will not disrupt a target chromatin, or a structural or functional feature of a target chromatin. Methods of designing a chromatin component and a tag capable of binding the chromatin component that does not disrupt a chromatin of the invention may depend on the particular application of a method of the invention, and may be determined experimentally. For instance, if an application of a method of the invention comprises promoter function, a tag may be designed to bind anywhere adjacent to the promoter, but without disrupting the promoter.

In an embodiment, a tag of the invention comprises a nucleic acid sequence capable of binding a nucleic acid sequence component of a target chromatin, wherein the nucleic acid sequence component of the chromatin is normally present in a cell of the invention. Non-limiting examples of nucleic acids capable of binding a nucleic acid sequence component of a chromatin include antisense RNA or DNA nucleic acids, and modified nucleic acids and nucleic acid mimics such as peptide nucleic acids, locked nucleic acids, phosphorodiamidate morpholino oligomers (PMO). In some embodiments, a tag of the invention comprises a nucleic acid sequence comprising locked nucleotides. For instance, a nucleic acid sequence comprising locked nucleotides may be as described in US20110262908 or US20120040857, and a peptide nucleic acid tag may be as described in Boffa et al. 1995 PNAS 92:1901-1905, the disclosures of all of which are incorporated herein in their entirety. Importantly, a non-functional tag of the invention lacks the nucleic acid component of the tag such that the non-functional tag is not capable of specifically recognizing a nucleic acid sequence component of a target chromatin.

In specific embodiments, a tag of the invention comprises a guide RNA (gRNA) capable of binding a nucleic acid sequence component of a chromatin, wherein the nucleic acid sequence component of the chromatin is normally present in a cell of the invention. A gRNA may be part of the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) Type II system. There are two distinct components to this system: (1) a guide RNA and (2) an endonuclease, in this case the CRISPR associated (Cas) nuclease, Cas9. The guide RNA is a combination of the endogenous bacterial crRNA and tracrRNA into a single chimeric guide RNA (gRNA) transcript. The gRNA combines the targeting specificity of the crRNA with the scaffolding properties of the tracrRNA into a single transcript. When the gRNA and the Cas9 are expressed in the cell, the gRNA/Cas9 complex is recruited to the target sequence by the base-pairing between the gRNA sequence and the complement to the target sequence in the genomic DNA. For successful binding of Cas9, the genomic target sequence must also contain the correct Protospacer Adjacent Motiff (PAM) sequence immediately following the target sequence. The binding of the gRNA/Cas9 complex localizes the Cas9 to the genomic target sequence. Accordingly, guide RNA corresponds to a nucleic acid comprising a complementary sequence to a nucleic acid sequence component of a chromatin. In the present invention, guide RNA is engineered to comprise a sequence complementary to a portion of a nucleic acid sequence component of a chromatin such that it is capable of targeting the nucleic acid sequence component of a chromatin. In a particular embodiment, the guide RNA comprises a sequence of 5 to 50 nucleotides, preferably at least 12 nucleotides which is complementary to the nucleic acid sequence component of a chromatin. In a more particular embodiment, the guide RNA is a sequence of at least 30 nucleotides which comprises at least 10 nucleotides, preferably 12 nucleotides complementary to the nucleic acid sequence component of a chromatin. In certain embodiments, a target nucleic add sequence comprises a PAM sequence immediately following the nucleic acid sequence component of a chromatin. The typical length of the nucleic acid sequence component of a chromatin is about 20 base pairs, although sequences that are longer or shorter can be used.

A tag of the invention further comprises a protein that associates with the nucleic acid portion of the tag. Accordingly, a tag further comprises a protein capable of binding the nucleic acid portion of the tag, wherein the nucleic acid portion of the tag specifically recognizes a nucleic acid sequence normally found in a cell of the invention. The protein may be a wild type nucleic acid binding protein capable of binding a nucleic acid tag bound to a target chromatin. Alternatively, the protein may be engineered to have binding specificity for the nucleic acid portion of the tag. In preferred embodiments, the protein comprises a nuclease inactivated Cas9 protein, or derivatives thereof, wherein the Cas9 protein binds to the nucleic acid portion of the tag of the invention. In exemplary embodiments, a tag comprises Cas9, wherein Cas9 binds to guide RNA (gRNA). Importantly, the non-functional tag comprises the same protein as the functional tag of the invention.

A tag of the invention further comprises an affinity handle. An affinity handle may be used as an affinity purification handle for purifying a tagged target chromatin. Affinity handles may include any affinity handle for which a cognate binding agent is readily available. An affinity handle may be an aptamer, an antibody, an antibody fragment, a double-stranded DNA sequence, modified nucleic acids and nucleic acid mimics such as peptide nucleic acids, locked nucleic acids, phosphorodiamidate morpholino oligomers (PMO), a ligand, a ligand fragment, a receptor, a receptor fragment, a polypeptide, a peptide, a coenzyme, a coregulator, an allosteric molecule, non-immunoglobulin scaffolds such as Affibodies, Anticalins, designed Ankyrin repeat proteins and others, an ion, or a small molecule for which a cognate binding agent is readily available. The term “aptamer” refers to a polypeptide or a polynucleotide capable of binding to a target molecule at a specific region. It is generally accepted that an aptamer, which is specific in its binding to any polypeptide, may be synthesized and/or identified by in vitro evolution methods. Non limiting examples of handles that may be suitable for isolating a chromatin may include biotin or a biotin analogue such as desthiobiotin, digoxigenin, dinitrophenol or fluorescein, a macromolecule that binds to a nucleic acid or a nucleic acid binding protein such as the Lac repressor, a zinc finger protein, a transcription activator protein capable of binding a nucleic acid, or a transcription activator-like (TAL) protein, antigenic polypeptides such as protein A, or peptide ‘tags’ such as polyhistidine, FLAG, HA and Myc tags. In preferred embodiments, an affinity handle may be an antigenic polypeptide. In specific embodiments, an affinity handle may be the protein A antigenic polypeptide, or derivatives thereof. Due to the properties of an affinity handle, the affinity handle may also non-specifically associate with nucleic acid binding proteins. Importantly, the non-functional tag comprises the same affinity handle as the functional tag of the invention.

In specific embodiments, a tag of the invention comprises protein A as the affinity handle. In other specific embodiments, a tag of the invention comprises catalytically inactive Cas9 nuclease as the protein. In exemplary embodiments, a tag of the invention comprises protein A and a catalytically inactive Cas9 nuclease. In another exemplary embodiment, a tag of the invention comprises protein A tagged nuclease inactivated Cas9 protein and a gRNA which has been modified to bind a nucleic acid sequence normally found in a cell. In still another exemplary embodiment, a non-functional tag of the invention comprises protein A tagged nuclease inactivated Cas9 protein and does not comprise a gRNA. The Cas9 and gRNA of the invention may be components of the CRISPR system as discussed above.

A target chromatin may be contacted with a tag or non-functional tag at any time during a method of the invention leading to isolation of target chromatin. For instance, a target chromatin may be contacted with a tag or non-functional tag during cell culture by expressing the tag or non-functional tag in a cell of the invention. Alternatively, a target chromatin may be contacted with a tag or non-functional tag after cell culture but before cell lysis, after cell lysis, or after fragmentation of chromatin to generate chromatin fragments comprising a target chromatin. In such embodiments, a tag or non-functional tag may be added to the cell culture or cell lysate as a recombinant protein. The recombinant protein may be expressed, isolated and purified via methods standard in the art for protein purification.

In some embodiments, a target chromatin is contacted with a tag or non-functional tag after cell culture but before cell lysis. As such, a tag or non-functional tag may be introduced into a cell before cell lysis. Methods of introducing a tag or non-functional tag into a cell of the invention can and will vary depending on the type of cell, the tag, and the application of a method of the invention. For instance, a nucleic acid (i.e. a plasmid) capable of expressing a tag or non-functional tag of the invention may be introduced into a cell after culture such that the tag or non-functional tag is expressed during cell culture. In other embodiments, a target chromatin is contacted with a tag or non-functional tag after cell lysis. In yet other embodiments, a target chromatin is contacted with a tag or non-functional tag after cell lysis and chromatin fragmentation. In both of the foregoing embodiments, the tag or non-functional tag may be introduced as a recombinant protein. In specific embodiments, a target chromatin is contacted with a tag or non-functional tag during cell culture by expressing the tag or non-functional tag in a cell of the invention during cell culture. In an exemplary embodiment, a target chromatin is contacted with a tag during cell culture by expressing a tag comprising a gRNA, inactivated Cas9, and an affinity handle in a cell of the invention during cell culture. In another exemplary embodiment, a target chromatin is contacted with a non-functional tag during cell culture by expressing a tag comprising an inactivated Cas9 and an affinity handle in a cell of the invention during cell culture, wherein the non-functional tag does not comprise a gRNA.

(d) Preparation of Cell Lysate

According to the invention, affinity handle bound to a tagged target chromatin bound to nucleic acid binding proteins and affinity handle bound to non-specific nucleic acid binding proteins in a first cell sample is isolated and affinity handle bound to non-specific nucleic acid binding proteins in a second cell sample is isolated. The method of isolating affinity handle in a first cell sample and second cell sample may be performed on a cell lysate derived from a cell sample. A skilled practitioner of the art will appreciate that structural and functional features of an affinity handle and a tagged target chromatin must be preserved during cell lysis and isolation of the affinity handle and the tagged target chromatin. The association of proteins with a tagged target chromatin may be preserved during cell lysis using methods known in the art for preserving a complex of proteins with a nucleic acid sequence. For instance, lysing of a cell may be performed under refrigeration or using cryogenic methods and buffer conditions capable of preserving association of proteins and nucleic acid sequences. In addition, a complex of proteins with a nucleic acid may be preserved by crosslinking protein and nucleic acid complexes in a cell prior to lysing. Crosslinking protein and nucleic acid complexes in a cell may also capture, or preserve, transient protein-protein and protein-nucleic acid interactions.

In some embodiments, a complex of proteins with a nucleic acid may be preserved by crosslinking protein and nucleic acid complexes in a chromatin prior to lysing a cell and isolating the affinity handle and target chromatin. Crosslinking is the process of joining two or more molecules such as two proteins or a protein and a nucleic acid molecule, by a covalent bond. Molecules may be crosslinked by irradiation with ultraviolet light, or by using chemical crosslinking reagents. Chemical crosslinking reagents capable of crosslinking proteins and nucleic acids are known in the art and may include crosslinking reagents that target amines, sulfhydryls, carboxyls, carbonyls or hydroxyls; omobifunctional or heterobifunctional crosslinking reagent, variable spacer arm length or zero-length crosslinking reagents, cleavable or non-cleavable crosslinking reagents, and photoreactive crosslinking reagents. Non-limiting examples of crosslinking reagents that may be used to crosslink protein complexes and/or protein complexes and nucleic acids may include formaldehyde, glutaraldehyde, disuccinimidyl glutarate, disuccinimidyl suberate, a photoreactive amino acid such as photo-leucine or photo-methionine, and succinimidyl-diazirine. The degree of crosslinking can and will vary depending on the application of a method of the invention, and may be experimentally determined.

In a preferred embodiment, a complex of proteins with a nucleic acid in a chromatin of the invention may be preserved by crosslinking protein and nucleic acid complexes in a cell prior to lysing using formaldehyde. In an exemplary embodiment, a complex of proteins with a nucleic acid in a chromatin of the invention may be preserved by crosslinking protein and nucleic acid complexes in a cell prior to lysing using formaldehyde as described in the examples.

A skilled practitioner of the art will appreciate that protocols for lysing a cell can and will vary depending on the type of cell, the target chromatin of the invention, and the specific application of a method of the invention. Non-limiting examples of methods that may be used to lyse a cell of the invention may include cell lysis using a detergent, an enzyme such as lysozyme, incubation in a hypotonic buffer which causes a cell to swell and burst, mechanical disruption such as liquid homogenization by forcing a cell through a narrow space, sonication, freeze/thaw, mortar and pestle, glass beads, and combinations thereof. In some embodiments, when a cell of the invention is a yeast cell, the cell may be cryogenically lysed under liquid nitrogen temperature with glass beads. In exemplary embodiments, when a cell of the invention is a yeast cell, the cell may be cryogenically lysed under liquid nitrogen temperature with glass beads as described in the examples.

Buffer conditions used during lysing and isolation of a chromatin of the invention can and will be altered to control stringent conditions during cell lysis and isolation to preserve association of proteins and nucleic acid sequences of a chromatin. “Stringent conditions” in the context of chromatin isolation are conditions capable of preserving specific association of proteins and nucleic acids of a chromatin, but minimizing non-specific association of proteins and nucleic acids. Stringent condition can and will vary depending on the application of a method of the invention, the target chromatin of the invention, the nucleic acid sequence in a target chromatin, the proteins or protein complexes associated with a target chromatin of the invention, whether or not proteins, protein complexes and nucleic acid sequences are crosslinked, and the conditions used for crosslinking proteins, protein complexes and nucleic acid sequences of a target chromatin. For instance, more stringent buffer conditions may be used in a method of the invention wherein proteins, protein-protein complexes, and protein-nucleic acid complexes are crosslinked compared to a method of the invention wherein proteins, protein-protein complexes, and protein-nucleic acid complexes are not crosslinked. As such, stringent buffer conditions used during cell lysis and isolation of a nucleic acid sequence of the invention may be experimentally determined for each application wherein a method of the invention is used. Buffer conditions that may alter stringent conditions during cell lysis and isolation may include pH and salt concentration. In preferred embodiments, proteins, protein-protein complexes, and protein-nucleic acid complexes of a target chromatin of the invention are crosslinked, and stringent buffer conditions are used during lysis and isolation of a chromatin of the invention. In exemplary embodiments, proteins, protein-protein complexes, and protein-nucleic acid complexes of a target chromatin of the invention are crosslinked, and stringent buffer conditions are used during lysis and isolation of a chromatin of the invention and are as described in the examples. In an exemplary embodiment, a first cell sample and a second cell sample are crosslinked to stabilize protein-protein and protein-nucleic acid interactions with a target chromatin, then the first cell sample and the second cell sample are lysed, and then the target chromatin in the first cell sample and the second cell sample is fragmented resulting in 500 to 1500 base pair fragments.

(e) Chromatin Isolation

According to the invention, the method of isolating an affinity handle from each cell sample may be performed on cell lysates derived from the cell samples. As described in Sections III(d) above, a cell lysate comprises a lysate of a cell sample, wherein a target chromatin is tagged in one of the lysates, or one of the cell samples. A cell lysate also comprises a lysate of a cell sample, wherein a target chromatin is not tagged in one of the lysates, or one of the cell samples.

Isolating an affinity handle may enrich for a tagged target chromatin. An affinity handle bound to a tagged target chromatin may be isolated from a mixture of chromatins or chromatin fragments in a cell lysate. As used herein, the term “isolated” or “purified” may be used to describe a purified preparation of a target chromatin that is enriched for the target chromatin, but wherein the target chromatin is not necessarily in a pure form due to the presence of non-specifically bound nucleic acid binding proteins. A target chromatin of the present invention may be purified to homogeneity or other degrees of purity. In general, the level of purity of an isolated target chromatin can and will vary depending on the cell type, the specific chromatin to be isolated, and the intended use of a target chromatin of the invention. The level of purity of an isolated target chromatin may be determined using methods known in the art. For instance, the level of purity of an isolated target chromatin may be determined by determining the level of purity of a nucleic acid sequence associated with a target chromatin, by determining the level of purity of a protein associated with a target chromatin, or by determining the level of enrichment of a target chromatin, compared to a non-target chromatin in a cell. In preferred embodiments, the level of purity of an isolated target chromatin is determined by determining the level of enrichment of a target chromatin, compared to a non-target chromatin in a cell.

For example, an isolated target chromatin is not necessarily 100% pure, but may be about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90% pure. An isolated target chromatin may be enriched for the target chromatin, relative to a chromatin in the lysed preparation that was contacted with a non-functional tag of the invention. An isolated target chromatin may be enriched by 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 fold relative to a chromatin that was contacted with a non-functional tag of the invention. In some embodiments, an isolated target chromatin is enriched by 10, 20, 30, 40 or 50 fold relative to a chromatin that was contacted with a non-functional tag of the invention. In other embodiments, an isolated target chromatin is enriched by 50, 60, 70, 80, 90, or 100 fold relative to a chromatin that was was contacted with a non-functional tag of the invention. In an exemplary embodiment, an isolated target chromatin is enriched 60, 65, 70, 75 or 80 fold relative to a chromatin that was contacted with a non-functional tag of the invention.

An affinity handle may be isolated using methods known in the art, such as electrophoresis, molecular, immunological and chromatographic techniques, ion exchange, hydrophobic, affinity, and reverse-phase HPLC chromatography, size exclusion chromatography, precipitation, dialysis, chromatofocusing, ultrafiltration and diafiltration techniques, and combinations thereof. For general guidance in suitable purification techniques, see Scopes, R., Protein Purification, Springer-Vertag, NY (1982).

In general, a method of the invention comprises isolating an affinity handle by affinity purification, or affinity purification in combination with other methods of isolating chromatin described above. In a preferred embodiment, a method of the invention comprises isolating an affinity handle by affinity purification. Non limiting examples of affinity purification techniques that may be used to isolate an affinity handle may include affinity chromatography, immunoaffinity chromatography, size exclusion chromatography, and combinations thereof. See, for example, Roe (ed), Protein Purification Techniques: A Practical Approach, Oxford University Press, 2nd edition, 2001.

A target chromatin contacted and bound by a tag may be isolated using any affinity purification method known in the art. In short, a target chromatin is bound to an affinity handle capable of binding to a substrate. The substrate comprising a bound affinity handle bound to target chromatin may then be washed to remove non-target chromatin and other cell debris, and the target chromatin may be released from substrate. Methods of affinity purification of material comprising an affinity handle are known in the art and may include binding the affinity handle to a substrate capable of binding the affinity handle. The substrate may be a gel matrix such as gel beads, the surface of a container, or a chip. The target chromatin bound to the affinity handle may then be purified. Methods of purifying tagged molecules are known in the art and will vary depending on the target molecule, the tag, and the substrate. For instance, if the affinity handle is bound to a target chromatin, the affinity handle may be bound to a magnetic bead substrate comprising IgG, and purified using a magnet. Importantly, the non-functional tag comprising an affinity handle in the second cell sample is subjected to the same affinity purification method as the first cell sample.

(f) Protein Extraction, Identification, and Determination of Labeling

Proteins and peptides associated with an isolated tagged target chromatin are extracted from the isolated tagged target chromatin. Methods of extracting proteins from chromatin are generally known in the art of protein biochemistry. Generally, any extraction protocol suitable for isolating proteins and known to those of skill in the art may be used. Extracted proteins may also be further purified before protein identification. For instance, protein extracts may be further purified by differential precipitation, differential solubilization, ultracentrifugation, using chromatographic methods such as size exclusion chromatography, hydrophobic interaction chromatography, ion exchange chromatography, affinity chromatography, metal binding, immunoaffinity chromatography, HPLC, or gel electrophoriesis such as SDS-PAGE and QPNC-PAGE. In a preferred embodiment, extracted proteins are further purified using SDS-PAGE.

Extracted and purified intact proteins and post-translational modification of proteins may then be identified. Alternatively, extracted and purified intact proteins may be further digested, and the resulting peptide fragments are identified. In some embodiments, intact extracted proteins are identified. In preferred embodiments, extracted proteins are further digested, and the resulting peptide fragments are identified. For instance, protein extracts may be fragmented by enzymatically digesting the proteins using a protease such as trypsin. In exemplary embodiments, extracted proteins are further digested as described in the examples.

Methods of identifying proteins or protein fragments are known in the art and may include mass spectrometry (MS) analysis, or a combination of mass spectrometry with a chromatographic technique. Non limiting examples of mass spectrometer techniques may include tandem mass spectrometry (MS/MS), matrix-assisted laser desorption/ionization source with a time-of-flight mass analyzer (MALDI-TOF), inductively coupled plasma-mass spectrometry (ICP-MS), accelerator mass spectrometry (AMS), thermal ionization-mass spectrometry (TIMS), isotope ratio mass spectrometry (IRMS), and spark source mass spectrometry (SSMS). Chromatographic techniques that may be used with MS may include gas chromatography, liquid chromatography, and ion mobility spectrometry. In a preferred embodiment, proteins may be identified using tandem mass spectrometry in combination with liquid chromatography (LC-MS/MS). In another preferred embodiment, post-translational modification of proteins may be identified using tandem mass spectrometry in combination with liquid chromatography (LC-MS/MS).

In the present invention, the method of label-free proteomics is used to categorize whether proteins enriched with a section of chromatin are specific or contaminant. Label-free methods of quantifying proteins or protein fragments are known in the art. In label-free quantitative proteomics, each sample is separately prepared, then subjected to individual methods of identifying proteins or protein fragments which may include LC-MS/MS or LC/LC-MS/MS. According to the invention, one sample comprises a target chromatin that is tagged in the cell sample and one sample comprises a target chromatin that is untagged in the cell sample. Label-free protein quantification is generally based on two categories of measurement. In the first are the measurements of ion intensity changes such as peptide peak areas or peak heights in chromatography. The second is based on the spectral counting of identified proteins after MS/MS analysis. Peptide peak intensity or spectral count is measured for individual LC-MS/MS or LC/LC-MS/MS runs and changes in protein abundance are calculated via a direct comparison between different analyses. In a preferred embodiment, the proteins identified using mass spectrometry are quantified and identified as enriched in the sample containing the tagged target chromatin compared to the sample containing the untagged target chromatin using label-free proteomics. In an exemplary embodiment, the proteins identified using mass spectrometry are quantified and identified as enriched in the sample containing the tagged target chromatin compared to the sample containing the untagged target chromatin using spectral counting.

The method of protein quantification by spectral count is known in the art and is reviewed in Zhu et al., J Biomed Biotechnol 2010, which is incorporated by reference herein. In spectral counting, relative protein quantification is achieved by comparing the number of identified MS/MS spectra from a protein of one sample to the same protein in the other sample. In the present invention, one sample comprises a target chromatin that is tagged and another sample comprises a target chromatin that is untagged. Protein quantification in spectral counting utilizes the fact that an increase in protein abundance typically results in an increase in the number of its proteolytic peptides, and vice versa. This increased number of (tryptic) digests then usually results in an increase in protein sequence coverage, the number of identified unique peptides, and the number of identified total MS/MS spectra (spectral count) for each protein.

As such, determining the abundance of an identified protein in a tagged chromatin sample compared to the same protein in an untagged chromatin sample, may determine if the protein was specifically associated with a target chromatin of the invention. If an identified protein associated with a target chromatin is in enriched in a tagged chromatin sample compared to the same protein in an untagged chromatin sample, then the protein was specifically associated with a target chromatin of the invention. If an identified protein is not enriched in a tagged chromatin sample compared to an untagged chromatin sample, then the protein is non-specifically associated with a target chromatin of the invention.

A skilled artisan in spectral counting will appreciate that normalization and statistical analysis of spectral counting datasets are necessary for accurate and reliable detection of protein changes. Since large proteins tend to contribute more peptide/spectra than small ones, a normalized spectral abundance factor (NSAF) is defined to account for the effect of protein length on spectral count. NSAF is calculated as the number of spectral counts (SpC) identifying a protein, divided by the protein's length (L), divided by the sum of SpC/L for all proteins in the experiment. NSAF allows the comparison of abundance of individual proteins in multiple independent samples and has been applied to quantify the expression changes in various complexes.

In the present invention, to measure enrichment of a protein, the normalized spectral abundance factor (NSAF) is calculated for each protein in each lane of an SDS-PAGE gel by dividing the number of spectral counts (normalized for the size of the protein) of a given protein by the sum of all normalized spectral counts of all proteins in the gel lane. The enrichment level for each protein is identified by calculating the fold enrichment (tagged chromatin/untagged chromatin) using the NSAF values. In an exemplary embodiment, proteins enriched in a sample containing a tagged target chromatin compared to a sample containing an untagged target chromatin are enriched by at least about 2 fold. In other embodiments, proteins enriched in a sample containing a tagged target chromatin compared to a sample containing the untagged target chromatin are enriched by at least about 1.5 fold. In other embodiments, proteins enriched in a sample containing a tagged target chromatin compared to a sample containing an untagged target chromatin are enriched by at least about 3 fold, about 4 fold, about 5 fold, about 6 fold, about 7 fold, about 8 fold, about 9 fold, about 10 fold, about 11 fold, about 12 fold, about 13 fold, about 14 fold, about 15 fold, about 16 fold, about 17 fold, about 18 fold, about 19 fold or about 20 fold. As such, a protein enriched by at least about 2 fold in a tagged chromatin sample compared to an untagged chromatin sample, is specifically associated with the chromatin. For instance, a baseline for non-specifically associated proteins may be proteins enriched by less than about 1.5 fold in a tagged chromatin sample compared to an untagged chromatin sample, wherein one or more proteins are not associated with chromatin. Non-limiting examples of proteins not associated with a chromatin may include enzymes required for metabolism, receptors, and ribosomal proteins. In preferred embodiments, proteins not associated with a chromatin are ribosomal proteins, and a baseline for non-specifically associated proteins is an enrichment less than about 1.5 fold in a tagged chromatin sampled compared to an untagged chromatin sample. In an exemplary embodiment, proteins or protein fragments enriched by at least 15 fold in a tagged chromatin sample compared to an untagged chromatin sample are specifically associated with a target chromatin.

In preferred embodiments, a target chromatin is tagged in one cell sample and a target chromatin is not tagged in a second cell sample, and MS analysis is used to identify proteins or protein fragments isolated during affinity purification of each sample, and label-free proteomics is used to determine if a protein or a protein fragment is specifically or non-specifically associated with the target chromatin. Methods of deriving MS data to identify proteins or protein fragments are known in the art, and may include using known computational techniques to distill MS data such as Mascot Distiller, Rosetta Elucidator, and MaxQuant.

A method of the invention may be performed on the biological sample. The identification of proteins specifically associated with a target chromatin may be compared to a reference sample, wherein when the reference sample is from a diseased subject, the proteins specifically associated with a target chromatin are the same or wherein when the reference sample is from a non-diseased subject, the proteins specifically associated with a target chromatin are different, then the subject may be diagnosed with the disease.

Additionally, a method of the invention may be used to understand the proteins involved in chromosomal architecture.

In some embodiments, a method of the invention is used to determine differences in chromatin structure and function between a transcriptionally silent and a transcriptionally active state of a genomic locus. As such, proteins specifically associated with a genomic locus, and post-translational modifications of proteins associated with a chromatin comprising the genomic locus may be determined in cells comprising a transcriptionally silent state of a genomic locus, and in cells comprising a transcriptionally active state of a genomic locus.

Introduction for Examples 1-3

It has long been appreciated that chromatin-associated proteins and epigenetic factors play central roles in cell-fate reprogramming of genotypically identical stem cells through lineage-specific transcription or repression of precise genes and large chromosomal regions (Martin, 1981; Ho and Crabtree, 2010; Rossant, 2008). However, the hierarchy of chromatin-templated events orchestrating the formation and inheritance of different epigenetic states remains poorly understood at a molecular level. Since misregulation of chromatin structure and post-translational modification of histones (PTMs) is linked to cancer and other epigenetic diseases (Jones and Baylin, 2007; Chi et al., 2010), it is imperative to establish new methodologies that will allow comprehensive studies and unbiased screens for participants in epigenetic mechanisms. Unfortunately, defining how chromatin regulators collectively assemble and operate on a precise region of the genome is difficult to elucidate; there are no current methodologies that allow for determination of all proteins present at a defined, small region of chromatin.

Technical challenges have precluded the ability to determine positioning of chromatin factors along the chromosome. Chromatin immunoprecipitation (ChIP) assays have been used to better understand genome-wide distribution of proteins and histone modifications within a genome at the nucleosome level (Dedon at al., 1991; Ren et al., 2000; Pokholok et al., 2005; Robertson et al., 2007; Johnson et al., 2007; Barski at al., 2007; Mikkelsen et al, 2007). However, major drawbacks of ChIP-based chromatin enrichment methods include experiments that are largely confined to examining singular histone PTMs or proteins rather than simultaneous profiling of multiple targets, the inability to determine the co-occupancy of particular histone PTMs, and that ChIP is reliant on the previous identification of the molecular target. Affinity purification approaches have been devised for the isolation of a chromatin region (Griesenbeck et al., 2003; Agelopoulos et al., 2012); however, these approaches were not done at a level for proteomic analysis and they do not provide a mechanism for determining the specificity of protein interactions. More recently, groups biochemically enriching for intact chromatin have reported characterization of proteins associated with large chromatin structures such as telomeres (Dejardin and Kingston, 2009) and engineered plasmids (Akiyoshi el al., 2009; Unnikrishnan et al., 2010); however, these approaches do not enrich for a small integrated genomic locus and do not employ specialized mass spectrometric techniques to detect protein contamination in purified material.

We sought to compare differences in chromatin between the transcriptionally active and silent states of a single genomic locus, and developed a technology, called chromatin affinity purification with mass spectrometry (ChAP-MS). ChAP-MS provides for the site-specific enrichment of a given ˜1,000 base pair section of a chromosome followed by unambiguous identification of both proteins and histone PTMs associated with this chromosome section using highly selective mass spectrometry. Using ChAP-MS, we were able to purify chromatin at the Saccharomyces cerevisiae GAL.1 locus in transcriptionally silent and active states. We identified proteins and combinatorial histone PTMs unique to each of these functional states and validated these findings with ChIP. The ChAP-MS technique will greatly improve the field of epigenomics as an unbiased approach to study regulatory mechanisms on chromatin.

Example 1. ChAP-MS Technology

FIG. 1A provides an overview of the ChAP-MS approach that was used to screen for proteins and histone PTMs associated with a specific genomic locus in transcriptionally active or repressive states. A LexA DNA binding site was engineered immediately upstream of the GAL1 start codon in a S. cerevisiae strain constitutively expressing a LexA-Protein A (LexA-PrA) fusion protein. The LexA DNA binding site directs the localization of the LexA-PrA protein affinity “handle” to the GAL1 promoter in vivo. The positioning of the LexA DNA was designed to specifically enrich for chromatin-associated proteins and histone PTMs regulating gene expression near the transcriptional start site of GAL1. This strain was cultured in glucose to repress gene transcription, or galactose to activate gene transcription. Following in vivo chemical crosslinking to preserve the native protein-protein interactions at GAL1 promoter chromatin, the chromatin was sheared to ˜1,000 base pair sections. The PrA moiety of the LexA-PrA fusion protein was then used to affinity purify the ˜1,000 base pair section of chromatin at the 5′ end of the GAL1 gene for high resolution mass spectrometric identification of proteins and histone PTMs. It was anticipated that culturing these cells in glucose would result in the isolation of proteins and PTMs correlated to silent chromatin, while culturing cells in the presence of galactose would purify histone PTMs and proteins, like RNA polymerase, that are involved with active gene transcription.

The GAL1 gene is present at one copy per haploid cell; due to the relative low abundance of the targeted chromatin region in cellular lysates, it was fully anticipated that proteins nonspecifically associating with GAL1 chromatin would complicate analysis of the resulting purified material. Copurification of nonspecifically associating proteins is one of the major complications of affinity purifications; however, isotopic labeling of media provides a means to gauge in vivo protein-protein interactions and quantitate differences in peptide abundance (Smart et al., 2009; Tackett et al., 2005a). The inventors had previously developed a variation of this labeling technique called iDIRT (isotopic differentiation of interactions as random or targeted) that provides a solution for determining which coenriched proteins are specifically or nonspecifically associated with a complex of proteins (Smart et al., 2009; Tackett et al., 2005a). The iDIRT technique was adapted (as described in FIG. 1B) to control for proteins nonspecifically enriching with LexA-PrA and the resin. By using this adaptation of iDIRT on chromatin enriched from active and repressed chromatin states, the proteins nonspecifically enriching with the isolated GAL1 chromatin section were identified. The strain containing the LexA DNA binding site and LexA-PrA fusion protein was cultured in isotopically light media, while a strain lacking the LexA DNA binding site (but still containing the LexA-PrA fusion protein) was cultured in isotopically heavy media (¹³C₆ ¹⁵N₂-lysine). Following isolation of the cells, the light and heavy strains were mixed and colysed. The growth and mixing of light/heavy strains was performed separately under glucose and galactose growth conditions. The affinity purification of the GAL1 chromatin was performed from this mixture of light/heavy lysates. Proteins and histone PTMs specifically associated with the GAL1 chromatin containing the LexA DNA binding site were isotopically light as they arose from the cells grown in light media. Proteins that were nonspecific to the purification were a 1:1 mix of light and heavy as they were derived equally from the light and heavy lysates. Analysis of peptides from the enriched proteins with high-resolution mass spectrometry was used to determine the level of isotopically light and heavy proteins, thereby determining whether the detected protein was either a specific in vivo constituent of GAL1 chromatin or a nonspecific contaminant.

Example 2. Affinity Purification of a Specific Chromosome Section

To provide for enrichment of a specific chromosome section, a DNA affinity handle was engineered at the GAL1 gene in S. cerevisiae (FIG. 2A). A LexA DNA binding site was inserted via homologous recombination just upstream of the GAL1 start codon to create strain LEXA::GAL1. To create this strain, GAL1 was genomically deleted with URA3 in the W303a background, and then the GAL1 gene was reinserted with the upstream LEXA DNA sequence by homologous recombination. A plasmid constitutively expressing LexA-PrA was introduced into the strain to create LEXA::GAL1 pLexA-PrA (FIG. 2A). This strain provides a DNA affinity handle at the GAL1 gene and a protein affinity handle for specific enrichment. To determine if insertion of this LexA DNA binding site at GAL1 affected gene transcription, LEXA::GAL1 pLexA-PrA was cultured in glucose to repress gene transcription at GAL1, and separately in galactose to activate transcription. From these growths, cDNA was prepared and real-time PCR was used to measure the activation of GAL1 transcription in the presence of galactose (FIG. 2B). Insertion of the LexA DNA binding site just upstream of the GAL1 start codon did not drastically affect the activation of gene transcription; thus, this strain was used for ChAP-MS purification of GAL1 chromatin in the transcriptionally active and silent states.

To determine the effectiveness of isolation of GAL1 chromatin, the stringency and specificity of different purification conditions was analyzed. Purification of protein complexes under increasing stringencies such as high salt levels provides for the isolation of fewer nonspecifically interacting proteins (Smart et al., 2009; Taverna et al., 2006). Since the proteins purified with GAL1 chromatin will be chemically crosslinked, the stringency of the purification can potentially be quite high. Indeed, ChIP-qPCR against GAL1 showed that the PrA-based purification can survive relatively stringent conditions (FIG. 3A). From these studies, 1M NaCl and 1M urea were selected for future purifications, as these conditions are quite stringent and provide for enrichment of the GAL1 chromatin. Using an identical ChIP approach, the specificity of the GAL1 chromatin enrichment was determined (FIG. 3B). Using primers targeted to the indicated regions of chromatin surrounding GAL1, it was detected that the first 1,000 base pair section of the GAL/gene was indeed enriched. Enrichment of GAL1 chromatin was observed at a similar level under glucose and galactose growth conditions (FIG. 3C). The slightly less efficient isolation under galactose growth conditions may reflect availability of the DNA affinity site due to alterations in chromatin structure.

Example 3. ChAP-MS Analysis of Transcriptionally Active Anti Silent GAL1 Chromatin

Strain LEXA::GAL1 pLexA-PrA was subjected to the ChAP-MS procedure as outlined in FIG. 1. Strain LEXA::GAL1 pLexA-PrA was grown in isotopically light media, while strain pLexA-PrA was grown in isotopically heavy media. Following growth of each strain to mid-log phase, the cells were treated with 1.25% formaldehyde to trap protein interactions on the chromosomes. A detailed analysis of the amount of formaldehyde crosslinking required to preserve the in vivo state of chromatin during affinity purifications was recently published by the inventors (Byrum et al., 2011a, 2011b). Approximately 2.5×10¹¹ LEXA::GAL1 pLexA-PrA cells were mixed with an equivalent amount of isotopically heavy pLexA-PrA cells (separately for media containing glucose and galactose) and then subjected to lysis under cryogenic conditions with a Retch MM301 ball mill (Tackett et al., 2005a). Lysates were suspended in 20 mM HEPES (pH 7.4), 0.1% Tween 20, 1 M NaCl, 1 M urea, and 2 mM MgCl₂. Lysates were then subjected to sonication and chromatin was sheared to sections of ˜1,000 base pairs. LexA-PrA was collected on IgG-coated Dynabeads and coenriching proteins were resolved by SDS-PAGE and visualized by Coomassie staining (FIG. 4A). Gel lanes were sliced into 2 mm sections and subjected to in-gel trypsin digestion (Smart et al., 2009; Tackett et al., 2005a, 2005b). Peptides from proteins were identified by high-resolution mass spectrometry with a Thermo Velos Orbitrap mass spectrometer equipped with a Waters nanoACQUITY UPLC system. Proteins and PTM-containing peptides were identified and the level of isotopically light to heavy peptide was calculated with Mascot Distiller (Smart et al., 2009), Representative spectra are shown in FIG. 4B-D. Major bands observed in the gel lanes correspond to the affinity purification protein LexA-PrA and IgG chains as anticipated. Other proteins identified correspond to specifically and nonspecifically enriched proteins. Tables 1 and 2 list the proteins identified and percent isotopically light peptides (352 proteins from the glucose ChAP-MS and 399 proteins from the galactose ChAP-MS).

Once proteins were identified, a baseline was established for nonspecifically associated proteins in accordance to the iDIRT approach (Smart et al., 2009). Nonspecifically enriching ribosomal proteins were used to establish the nonspecifically associating baseline (Smart et al., 2009). The average percent isotopically light peptides from 20 ribosomal proteins from the glucose and galactose growth conditions were used to establish this nonspecifically associating baseline (Table 3). This resulted in a nonspecifically associating baseline of 49.93%±2.12% light for the glucose ChAP-MS and 66.8%±7.1% light for the galactose ChAP-MS (FIG. 5). Proteins were categorized as specifically associating with GAL1 chromatin if the percent light was greater than 2 SDs above the ribosomal level (Smart et al., 2009). FIG. 5 shows the proteins and histone PTMs specifically enriched with GAL1 chromatin under glucose and galactose growth conditions. Tables 4 and 5 list proteins that were identified as specifically enriched in both the glucose and galactose ChAP-MS analyses. Specifically enriched proteins or histone PTMs known to be involved in transcriptional regulation are listed in FIG. 5. For the glucose and galactose ChAP-MS analyses, 11 and 17 (respectively) additional proteins were detected as specifically enriched (FIG. 5, Tables 4 and 5). These additional proteins are abundant metabolic and heat shock proteins that are typical contaminants and false positives for this study. However, narrowing down 352 proteins identified from the glucose ChAP-MS and 399 proteins from the galactose ChAP-MS to 12 proteins and 27 proteins/PTMs specifically enriched produced a short list of candidates that was easily validated.

The ChAP-MS analyses of GAL1 chromatin revealed association of Gal3, Spt16, Rpb1, Rpb2, H3K14ac, H3K9acK14ac, H3K18acK23ac, H4K5acK8ac, and H4K12acK16ac under transcriptionally active conditions, while transcriptionally repressive conditions showed the enrichment of H3K36me3. In order to validate the ChAP-MS approach, standard ChIP was performed to specific interactions detected in the transcriptionally active and silent chromatin state at GAL1 (FIG. 6). These ChIP experiments validated the proteins and PTMs found associated with the transcriptionally active and repressed states of GAL1 chromatin determined from the ChAP-MS approach.

Discussion for Examples 1-3

The chromatin biology and epigenomics research communities have been limited to biased technologies that restrict targeted genome localization studies to previously identified proteins or histone PTMs. Here, a newly developed technology, called ChAP-MS, is described that circumvents this limitation by providing for isolation of a ˜1,000 base pair section of a chromosome for proteomic identification of specifically bound proteins and PTMs. In essence, the ChAP-MS approach allows one to take a “molecular snapshot” of chromatin dynamics at a specific genomic locus. Furthermore, employing this approach to target other chromatin regions will likely provide unprecedented insight on a variety of epigenetic regulatory mechanisms, chromatin structure, and genome metabolism.

Validation of the ChAP-MS Approach

The ChAP-MS approach was validated on the well-studied GAL1 locus in S. cerevisiae. The GAL1 gene is activated for gene transcription in the presence of galactose, while glucose represses transcription. Accordingly, it was rationalized that a purified ˜1,000 base pair section of chromatin at the 5′ end of the GAL1 gene from cells grown in galactose would contain histone PTMs correlated with active transcription and cellular machinery necessary for transcription, while the same chromatin section from cells grown in glucose would be enriched with histone PTMs associated with transcriptional repression. Prior publications have documented that H3 acetylation is enriched on the 5′ end of the active galactose-induced GAL1 gene, while in the presence of glucose it contains H3K36me3 (Shukla et al., 2006; Houseley et al., 2008). Results presented in the Examples herein with ChAP-MS, support each of these prior findings (FIG. 5). Furthermore, the presence of doubly acetylated histones (H3K9acK14ac, H3K18acK23ac, H4 K5acK8ac, H4K12acK16ac) during transcriptional activation was identified. This demonstrates how ChAP-MS may be used to study the combinatorial “code” of histone modifications at given chromosome regions without the need for prior identification of PTMs, PTM-specific antibodies, or sequential chromatin put-downs. Considering H4K12acK16ac for example, the identification of the double acetylation is unique to the ChAP-MS approach as antibodies to this double acetylation do not exist, thus one could not have performed a biased ChIP analysis. Additionally, it has been reported that commercially available antibodies to single acetylation at H4K12 or H4K16 are cross-reactive with other H4 acetylations and that double acetylation of H4K12K16 significantly alters the specificity of the antibody to the singly acetylated sites (Bock et al., 2011)—a limitation specific to antibodies used in biased ChIP studies and not to the unbiased ChAP-MS approach that uses quantitative mass spectrometric readout. The ChAP-MS approach simultaneously identified the presence of RNA polymerase (Rpb1, Rpb2) and FACT component Spt16 (which aids in reorganizing chromatin for RNA pol activity) under these transcriptionally active conditions. Also of interest was the identification of Gal3 at actively transcribing GAL1, which has previously been shown to inhibit the repressive activity of Gal80 at the GAL10/GAL1 locus (Platt and Reece, 1998). It was demonstrated how the ChAP-MS approach may be utilized to study chromatin dynamics at GAL1 under different states of gene transcription. Of particular interest for future functional studies may be the upstream activating sequence which binds the Gal4 actuator and Gal80 repressor which may allow better understand of the events surrounding the switch from repression to activation at GAL1 and GAL10, as well as the middle and 3′ end of GAL1 to understand the processes of elongation and termination, respectively.

Utility of ChAP-IViS as a General Tool for Studying Chromatin Biology

The ChAP-MS technology presented here demonstrates the ability to purify a unique chromosome section on the order of four to five nucleosomes in length from an in vivo source that can subsequently be subjected to sensitive proteomic studies. ChAP-MS has numerous advantages relative to traditional ChIP, including the ability to unbiasedly detect proteins/PTMs at a specific genomic locus and the identification of combinatorial histone modifications on a single histone molecule. Furthermore, ChAP-MS only requires approximately an order of magnitude more cells relative to biased ChIP studies, which is a huge advantage if doing more than ten blind ChIP studies at a given region is factored in (chances are many antibodies for many proteins would be heavily invested in, trying to guess a specifically bound protein/PTM). In this regard, ChAP-MS is a more cost-effective option for characterizing specifically bound proteins and histone PTMs relative to ChIP. Future derivations of this technology may employ targeted mass spectrometric approaches for better determination of combinatorial histone PTMs as well as identification of other regulatory PTMs on nonhistone proteins from these isolated sections (Taverna et al., 2007). Given the sensitivity of the mass spectrometry analysis employed and the relatively modest biological starting material, the findings presented in the Examples herein also establish a framework for applying ChAP-MS to profile across entire regions of chromosomes or investigate higher eukaryotic systems. Regardless, any advances that permit ChAP-MS analysis of in vivo untagged or unaltered samples, like tissues, will undoubtedly have valuable applications for investigating altered gene transcription mechanisms in human disease states, as this technique could provide a comprehensive way to intelligently identify targets for therapeutics.

Experimental Procedures for Examples 1-3 Construction of the LEXA::GAL1 pLexA-PrA Strain

The LEXA::GAL1 pLexA-PrA strain used to affinity enrich GAL1 chromatin was designed to have a LexA DNA binding site just upstream of the GAL1 start codon and contains a plasmid constitutively expressing a LexA-PrA fusion protein. In S. cerevisiae from the W303a background, the GAL1 gene was genomically replaced with URA3 using homologous recombination. Next, the GAL1 gene (+50 base pairs up and downstream) was PCR amplified with primers that incorporated a LexA DN binding site (5′-CACTTGATACTGTATGAGCATACAGTATAATTGC)(SEQ ID NO:1) immediately upstream of the GAL1 start codon. This LEXA::GAL1 cassette was transformed into the gal1::URA3 strain and selected for growth with 5-fluoroorotic acid, which is lethal in URA3 expressing cells. Positive transformants were sequenced to ensure homologous recombination of the cassette to create the LEXA::GAL1 strain. A plasmid that constitutively expresses LexA-PrA fusion protein with TRP selection was created by amplification of the PrA sequence from template pOM60 via PCR and subcloning into the Sac1/Sma1 ends of the expression plasmid pLexA-C. Transforming this plasmid into the LEXA:GAL1 strain gave rise to the LEXA:GAL1 pLexA-PrA strain. Additionally, a control used in these studies was W303a S. cerevisiae transformed only with pLexA-PrA.

Cell Culture

Strains LEXA:GAL1 pLexA-PrA and pLexA-PrA were grown in yeast synthetic media lacking tryptophan to mid-log phase at 30° C. LEXA:GAL1 pLexA-PrA strain growths were done with isotopically light lysine, while strain pLexA-PrA was cultured exclusively with isotopically heavy ¹³C6 ¹⁵N₂-lysine. For each strain, 12 l of media containing either 2% glucose or 3% galactose were grown to yield ˜5×10¹¹ cells per growth condition. At mid-log phase, the cultures were crosslinked with 1.25% formaldehyde for 5 min at room temperature and then quenched with 125 mM glycine for 5 min at room temperature. Cells were harvested by centrifugation (2,500×g) and frozen in liquid nitrogen as pellets in suspension with 20 mM HEPES (pH 7.4), 1.2% polyvinylpyrrolidone (1 ml/10 g of cell pellet). Frozen cell pellets were mixed as follows at 1:1 cell weight ratios: (1) LEXA:GAL1 pLexA-PrA isotopically light in glucose plus pLexA-PrA isotopically heavy control in glucose (2) LEXA:GAL1 pLexA-PrA isotopically light in galactose plus pLexA-PrA isotopically heavy control in galactose. Cell mixtures were cryogenically lysed under liquid nitrogen temperature with a Retsch MM301 ball mill (Smart et al., 2009; Tackett et al., 2005a).

ChAP-MS Procedure

Each of the following two cell lysates were processed for purification of GAL1 chromatin: (1) LEXA:GAL1 pLexA-PrA isotopically light in glucose plus pLexA-PrA isotopically heavy control in glucose, referred to as the glucose ChAP-MS, and (2) LEXA:GAL1 pLexA-PrA isotopically light in galactose plus pLexA-PrA isotopically heavy control in galactose, referred to as the galactose ChAP-MS. Twenty grams of frozen cell lysate (˜5×10¹¹ cells) was used for each of the glucose and galactose ChAP-MS analyses. ChAP-MS steps were performed at 4° C. unless otherwise noted. Lysates were resuspended in 20 mM HEPES (pH 7.4), 1 M NaCl, 2 mM MgCl₂, 1 M urea, 0.1% Tween 20, and 1% Sigma fungal protease inhibitor cocktail with 5 ml buffer per gram of frozen lysate. Lysates were subjected to sonication with a Diagenode Bioruptor UCD-200 (low setting, 30 s on/off cycle, 12 min total time) in 20 ml aliquots to yield ˜1 kb chromatin fragments. Supernatants from sonicated lysates were collected by centrifugation at 2,000×g for 10 min. Dynabeads (80 mg) coated with rabbit IgG were added to the lysates and incubated for 4 hr with constant agitation (Byrum et al., 2012a). Dynabeads were collected with a magnet and washed 5 times with the purification buffer listed above and 3 times with 20 mM HEPES (pH 7.4), 2 mM MgCl₂, 10 mM NaCl, 0.1% Tween 20. Washed Dynabeads were treated with 0.5 N ammonium hydroxide/0.5 mM EDTA for 5 min at room temperature to elute proteins. Eluants were lyophilized with a Savant SpeedVac Concentrator. Lyophilized proteins were resuspended in Laemmli SDS-PAGE loading buffer, heated to 95° C. for 20 min, resolved with 4%-20% tris-glycine Invitrogen precast gels, and visualized by colloidal Coomassie staining.

High-Resolution Mass Spectrometry and Data Analysis

Gel lanes were sliced into 2 mm sections and subjected to in-gel trypsin digestion (Byrum et al., 2011a, Byrum et al., 2011b, Byrum et al., 2012a; Tackett et al., 2005b). Peptides were analyzed with a Thermo Velos Orbitrap mass spectrometer coupled to a Waters nanoACQUITY liquid chromatography system (Byrum et al., 2011b). Using a data-dependent mode, the most abundant 15 peaks were selected for MS² from a high-resolution MS scan. Proteins were identified and the ratio of isotopically light/heavy lysine-containing tryptic peptide intensity was determined with Mascot and Mascot Distiller. The search parameters included: precursor ion tolerance 10 ppm, fragment ion tolerance 0.65 Da, fixed modification of carbamidomethyl on cysteine, variable modification of oxidation on methionine, and two missed cleavages possible with trypsin. A threshold of 95% confidence for protein identification, 50% confidence for peptide identification and at least two identified peptides per protein was used, which gave a 2% peptide false discovery rate. All specifically associating protein identifications and ratios were manually validated.

A baseline was established for nonspecifically associated proteins with nonspecifically enriched ribosomal proteins (Smart et al., 2009). The average percent isotopically light peptides from 20 ribosomal proteins from the glucose and galactose growth condition were used to establish this nonspecifically associated baseline. This resulted in a nonspecifically associated baseline of 49.93%±2.12% light for the glucose ChAP-MS and 66.8%±7.1% light for the galactose CHAP-MS. Proteins were categorized as specifically associating if the percent light was greater than 2 SDs above the ribosomal level (Tables 4 and 5) (Smart et al., 2009). Duplicate ChAP-MS procedures showed Pearson and Spearman correlation coefficient p values of <0.001.

ChIP and Gene Transcription Assays

ChIP and gene transcription assays were performed as previously reported (Tackett et al., 2005b; Taverna et al., 2006). Assays were performed in triplicate and analyzed by real time PCR.

Introduction for Examples 4-5

One of the most compositionally diverse structures in a eukaryotic cell is a chromosome. A multitude of macromolecular protein interactions and epigenetic modifications must properly occur on chromatin to drive functional aspects of chromosome biology like gene transcription, DNA replication, recombination, repair and sister chromatid segregation. Analyzing how proteins interact in vivo with chromatin to direct these activities and how epigenetics factors into these mechanisms remains a significant challenge owing to the lack of technologies to comprehensively analyze protein associations and epigenetics at specific native chromosome sites. Chromatin immunoprecipitation (ChIP) assays have traditionally been used to better understand genome-wide distributions of chromatin-associated proteins and histone post-translational modifications (PTMs) at the nucleosome level (Cermak et al., 2011). However, major drawbacks of current ChIP-based methods include their confinement to examining singular histone PTMs or proteins rather than simultaneous profiling of multiple targets, the inability of ChIP to directly determine the co-occupancy of particular histone PTMs and that ChIP is reliant on the previous identification and development of affinity reagents against the molecular target. A more comprehensive and unbiased approach would be the biochemical isolation of a specific native genomic locus for proteomic identification of proteins-associated and histone PTMs. Similar approaches have been performed for large structures like telomeres, engineered plasmids or engineered loci (Griesenbeck et al., 2003; Dejardin and Kingston, 2009; Hoshino and Fuji, 2009; Akiyoshi et al., 2009; Unnikrishnan et al., 2010; Byrum et al., 2012b); however, the proteomic analysis of a small native genomic region without genomic engineering has yet to be performed. To work toward proteomic studies of native chromatin regions (i.e. sections of chromatin that are unaltered genetically and spatially the genome), we recently developed a technique termed Chromatin Affinity Purification with Mass Spectrometry (ChAP-MS) that provides for the enrichment of a native 1-kb section of a chromosome for site-specific identification of protein interactions and associated histone PTMs (Byrum et al., 2012b). This ChAP-MS approach uses the association of an ectopically expressed affinity-tagged LexA protein with a genomically incorporated LexA DNA binding site for site-specific chromatin enrichment. The ChAP-MS approach provides for the isolation of chromatin from the native site in the chromosome; however, one must genomically engineer a LexA DNA binding site, which could alter the native state of the chromatin and which requires a biological system readily amendable to genomic engineering.

To alleviate genomic engineering for affinity enrichment of chromatin sections, we report the use of modified transcription activator-like (TAL) effector proteins to site-specifically target a native section of a chromosome for purification and proteomic analysis. We term this approach TAL-ChAP-MS (FIG. 7A). TAL effector proteins are from Xanthomonas, which infects plants and translocates TAL effectors into cells where they serve as transcription activators (Scholze and Boch, 2010; Scholze and Boch, 2011; Doyle et al., 2012). TALs contain a central domain of 18 tandem repeats of 34 amino acids each, which direct sequence-specific DNA binding (Doyle et al., 2012; Cermak et al., 2011). Binding to a given nucleobase in DNA is determined by two adjacent amino acids (12 and 13) within each of the 18 repeats (Scholze and Boch, 2010). Thus, by mutating these amino acids in each of the 18 tandem repeats, one can ‘program’ binding to a given 18-nt region of DNA in vivo. TAL proteins have been validated in cell culture for targeting nucleases for genome editing and for targeting transcription activators (Miller et al., 2011; Geissler et al., 2011). To test the ability of a TAL protein to serve as an affinity enrichment reagent for native chromatin isolation, a TAL protein was designed that bound a unique 18-nt region of DNA in the promoter region of the GAL1 gene in Saccharomyces cerevisiae (FIG. 7B). We chose to analyze proteins and histone PTMs regulating the galactose-induced gene transcription of GAL1 because (1) this is a well-studied genomic locus, which will provide for proof-of-principle analysis, and (2) we previously used this locus to develop the ChAP-MS technique (Byrum et al., 2012b); thus, a comparison can be made to the new TAL-ChAP-MS approach.

One of the major complications for studying specific protein associations with purified protein complexes or with chromatin is the co-enrichment of non-specifically associating proteins. This particularly becomes an issue when studying low copy number entities such as a single genomic locus. With the advancement of high-resolution and sensitive mass spectrometry in recent years, it has been suggested that >10⁹ cell equivalents are needed to study single genomic loci with proteomic approaches (Chait, 2011). In agreement, our ChAP-MS studies used 10¹¹ cells for isolation of GAL1 promoter chromatin at levels sufficient for proteomic analysis (Byrum et al., 2012b). When scaling up purifications of low copy entities to meet the sensitivity necessary for high-resolution mass spectrometric analysis, the issue of co-purifying abundant non-specific proteins becomes a major challenge. In the ChAP-MS approach (Byrum et al., 2012b), we used an isotope-labeling strategy to categorize whether a protein co-enriching with a section of chromatin was specifically associated or a contaminant. Limitations for isotope-labeling approaches are cost and having biological systems of study that are amendable to stable isotope-labeling with amino acids. To circumvent the use of isotope-labeling, we now have incorporated label-free quantitative mass spectrometry in the TAL-ChAP-MS workflow. The described TAL-ChAP-MS approach can therefore provide for the purification of a native chromatin region for label-free quantitative proteomic analysis, which will greatly simplify studies of how proteins and combinatorial histone PTMs regulate chromosome metabolism.

Example 4. Development of TAL-ChAP-MS

A schematic of the TAL-ChAP-MS approach to purify native chromatin for proteomic analysis is shown in FIG. 7A. To demonstrate the utility of the TAL-ChAP-MS approach, we used a TAL protein to target the promoter chromatin region upstream of the galactose-inducible GAL1 gene in S. cerevisiae (FIG. 7B). Yeast cells were grown in the presence of galactose to induce transcription of the GAL1 gene, which will recruit proteins and histone PTMs that activate transcription. A wild-type culture and a culture of cells containing a plasmid that expressed a PrA-tagged TAL protein that bound the GAL1 promoter region were grown and subjected to in vivo formaldehyde cross-linking to preserve chromatin structure during purification (Byrum et al., 2011a; Byrum et al., 2011b). Following cryogenic cell lysis and sonication of chromatin sections to ˜1 kb, each lysate was independently subjected to affinity enrichment of PrA with IgG-coated Dynabeads. Proteins co-enriching with TAL-PrA from the cells containing the pTAL-PrA plasmid and those enriching as contamination from the control cells with no plasmid were identified by high-resolution mass spectrometry. Using label-free quantitative analyses, the relative enrichment of proteins and histone PTMs specifically hound to the GAL1 promoter chromatin were identified.

Saccharomyces cerevisiae cells were transformed with pTAL-PrA, and protein expression was validated by western blotting (FIG. 7C). To evaluate whether TAL-PrA expression affected galactose-induced transcription of GAL1, cDNA was prepared from wild-type and wild-type (+pTAL-PrA) cells under glucose (transcriptionally repressed GAL1) and galactose (transcriptionally active GAL1) growth conditions. Quantitative rtPCR of this cDNA revealed that expression of TAL-PrA did not affect galactose-induced GAL1 transcription (FIG. 7D). To determine whether TAL-PrA enriched chromatin at the GAL1 promoter region, ChIP was performed to the PrA-tag in cells from glucose and galactose growths (FIG. 7E-G). Under transcriptionally active conditions, TAL-PrA specifically enriched chromatin from the GAL1 promoter region relative to sequences 2 kb up- and downstream (FIG. 7F). The level of chromatin enrichment by TAL-PrA under transcriptionally active conditions was similar to the level used for proteomic studies with LexA-PrA affinity enrichment in the ChAP-MS approach (Byrum et al., 2012b). Interestingly, the TAL-PrA protein did not show enrichment of the GAL1 promoter chromatin under transcriptionally repressive glucose growth conditions (FIG. 7G). One possibility of many is that the lack of enrichment could be due to inaccessibility of the TAL-PrA to the genomic target due to altered chromatin structure under transcriptionally repressive conditions—highlighting the importance for measuring specific chromatin enrichment of the TAL protein before using this approach for specific chromatin enrichment. In the previous publication of the ChAP approach (Byrum et al., 2012b), a LexA-PrA was targeted just upstream of the start codon of GAL1 for enrichment of chromatin, which showed enrichment under both glucose and galactose growth conditions. Importantly, the TAL used in the current study was targeted 193 bp upstream of the target site of LexA, which suggests that proximal regions may be differentially accessible to DNA-binding affinity reagents under various transcriptional states. In addition to analyzing enrichment of GAL1 chromatin relative to proximal sequences (FIG. 7E-G), enrichment of GAL1 chromatin was measured relative to the five most homologous sequences in the genome (Table 6). The GAL1 target DNA showed 4.6-fold better enrichment relative to the next five most similar sites in the genome—demonstrating specificity of the TAL protein used in this study to the targeted sequence at the GAL1 promoter region. Collectively, the data in FIG. 7C-G and Table 6 demonstrate that the TAL-ChAP-MS approach can provide enriched chromatin from the GAL1 promoter under transcriptionally active conditions that would be suitable for proteomic studies.

Example 5. Using TAL-ChAP-MS to Identify Proteins and Histone PTMs at the GAL1 Promoter

As detailed in the Experimental Procedures for Examples 4-5 section, chromatin from the transcriptionally active GAL1 promoter was enriched with TAL-PrA and resolved by SDS-PAGE (FIG. 8A). The similar Coomassie-stained protein pattern for the TAL-PrA and wild-type control samples in FIG. 8A demonstrates that the co-enrichment of contaminating proteins was a major issue for this approach. Accordingly, the label-free spectral counting approach described in the Experimental Procedures for Examples 4-5 section was used to identify proteins specifically enriched with the TAL-PrA. High-resolution mass spectrometry coupled with label-free proteomics was used to identify proteins and histone PTMs specifically enriched with the GAL1 promoter chromatin (FIG. 8B and Table 7). We focused our analysis on the top 10% of enriched proteins (54 proteins) that each showed >15-fold enrichment with the TAL-PrA (Table 7). Four of these 54 proteins (Rpb1, Rpb2, Spt16 and Gal3) are involved with active transcription of GAL1, and these are the same four proteins previously identified at the promoter of GAL1 with the ChAP-MS approach (Byrum et al., 2012b). Rpb1 and Rpb2 are RNA polymerise components, and Spt16 is a subunit of yFACT that aids in re-organizing chromatin for RNA polymerase activity. Gal3 has previously been shown to inhibit the repressive activity of Gal80 at GAL1 locus (Platt and Reece, 1998). Rpb1, Rpb2, Spt16 and Gal3 were confirmed to be associated adjacent to the TAL-PrA genomic binding site with standard ChIP (FIG. 8C). Thus, the TAL-ChAP-MS approach identified precisely the same proteins as the published ChAP-MS approach during transcriptional activation at the promoter of GAL1, thereby validating the TAL-ChAP-MS approach for studying the local proteome of small chromatin regions and the use of label-free proteomic approaches for quantifying such enrichments. Many of the other 50 proteins identified as >15-fold enriched with TAL-PrA are typical non-specific protein associations found in affinity purifications (e.g. highly abundant metabolic and ribosomal proteins).

In addition to protein associations with the GAL1 promoter, the following single histone PTMs were identified under transcriptionally active conditions: H3K14ac, H3K56ac, H3K79me1/me2/me3, H2BKI7ac and H2AK7ac; and the following combinatorial histone PTMs: H3K9acK14ac, H3K18acK23ac, H2BK6acK11ac and H2BK11acK17ac (FIG. 8B and Table 8). The presence of H3K14ac was confirmed by standard ChIP (FIG. 8C). Previously using ChAP-MS and routine ChIPs (Byrum et al., 2012b), a similar profile of singly acetylated H3 lysine residues was identified at the GAL1 promoter region, thus confirming the utility of the TAL-ChAP-MS approach. In addition to the acetylations observed in the ChAP-MS study, the TAL-ChAP-MS approach additionally identified methylation of H3K79. As previously reported for the ChAP-MS approach, the TAL-ChAP-MS approach uncovered combinatorial sets (i.e. multiple PTMs on single peptides) of histone PTMs under transcriptionally active conditions at the promoter of GAL1. The use of a technology like TAL-ChAP-MS to identify previously unknown combinatorial modifications is crucial to understand the epigenome, as specific antibodies to combinatorial histone PTMs are not usually available for standard approaches like ChIP. In general terms, acetylation of histone lysine residues and methylation of H3K79 correlate to transcriptional activation (Kouzarides, 2007); thus, the histone PTMs uncovered by TAL-ChAP-MS correlate to the active transcription state of GAL1 in the presence of galactose.

Discussion for Examples 4-5

We describe a novel approach called TAL-ChAP-MS that provides for the biochemical isolation of 1-kb native chromatin sections for proteomic identification of specifically associated proteins and combinatorial histone PTMs. The described TAL-ChAP-MS approach overcomes limitations of the ChAP-MS approach (Byrum et al., 2012b), as genomic engineering is not necessary for TAL-based affinity enrichment and because protein enrichment with a given locus can now be determined with label-free proteomics. Even without genomic engineering of the DNA, the ChAP-MS approach does require targeting of a DNA-binding affinity enrichment reagent (i.e. the TAL protein), which has the potential to perturb the chromatin state. However, the data in FIG. 7D demonstrate that transcription of GAL1 is not altered on TAL targeting, which supports maintenance of the chromatin integrity for the studies reported here. Targeting TALs to different sequences in adjacent genomic regions that would provide for purification of overlapping chromatin sections is one possible way for investigators to overcome concerns of TAL binding (i.e. a tiling approach). The implications of the TAL-ChAP-MS approach are far-reaching as investigators can now begin to elucidate the dynamics of chromatin regulation in a site-specific and comprehensive manner. Researchers will now only need to ‘reprogram’ the DNA-binding specificity of the TAL protein to obtain a unique affinity purification reagent for their chromosome region of interest. Using the TAL-ChAP-MS approach brings researchers closer to being able to take molecular ‘snapshots’ of the assembly and disassembly of proteins on chromatin and how epigenetic states are modulated at small genomic loci.

Experimental Procedures for Examples 4-5 pTAL-PrA Plasmid, Real-Time rtPCR and ChIP

For affinity enrichment of chromatin from the promoter region of the GAL1 gene in S. cerevisiae, a TAL protein was designed (by the GeneArt Precision TAL services of Life Technologies) to bind a unique 18-nt sequence (GGGGTAATTAATCAGCGA)(SEQ ID NO: 2) 193 base pairs upstream of the GAL1 open-reading frame (FIG. 7B). The TAL protein was designed as a truncation that lacked the native N-terminal transcription activation domain, but it contained the site-specific DNA-binding region. To develop an affinity enrichment reagent, the LexA-coding region of pLexA-PrA [plasmid that constitutively expresses a PrA-tagged LexA protein under TRP selection; from (Byrum et al., 2012b)] was replaced with the TAL-coding region to generate pTAL-PrA. Real-time qPCR measurement of galactose-induced transcription of GAL1 and all ChIP studies were performed as reported in (Byrum et al., 2012b).

TAL-ChAP-MS

To test the TAL-ChAP-MS approach at the promoter region of GAL1, wild-type and wild-type (+pTAL-PrA) S. cerevisiae (W303 matA) cells were cultured to mid-log phase in 3% galactose-containing media, subjected to 1.25% formaldehyde cross-linking, cryogenically lysed and subjected to sonication to shear genomic DNA to ˜1 kb [as detailed in (Byrum et al., 2012b; Byrum et al., 2011a; Byrum et al., 2011b)]. Immunoglobulin G (IgG)-coated Dynabeads were added to lysate from ˜10¹¹ cells from each growth separately [as detailed in (Byrum et al., 2012b)]. Proteins co-enriching with the TAL-PrA (wild-type cells +pTAL-PrA lysate) or proteins non-specifically binding to the Dynabeads (wild-type cell lysate) were resolved by SDS-PAGE/Coomassie-staining (FIG. 8A), excised as 2-mm bands from the entire gel lane, digested in-gel with trypsin and subjected to high-resolution tandem mass spectrometric analysis with a Thermo Velos Orbitap mass spectrometer [as reported in (Byrum et al., 2012b)]. Proteins and typical histone PTMs (lysine acetylation and methylation) were identified using Mascot (Tables 7 and 8). To measure enrichment of a protein, the normalized spectral abundance factor (Zybailov et al., 2006) was calculated for each protein in each lane by dividing the number of spectral counts (normalized for the size of the protein) of a given protein by the sum of all normalized spectral counts of all proteins in the gel lane (Byrum et al., 2011c). The enrichment level for each protein was identified by calculating the fold enrichment (TAL-PrA/wild type) using the normalized spectral abundance factor values (Table 7). Proteins with a fold enrichment >2 (511 of 1459 proteins identified) were used to generate a quantile plot of fold enrichment with GAL1 promoter chromatin (FIG. 8B).

Introduction for Example 6

For the work presented, a “local epiproteome” refers to not only the histone PTMs at a specific chromosomal location that are involved in a particular activity (Dai and Rasmussen, 2007), but also to the other proteins associated with the region in addition to the histones. Identifying the components of a specific epiproteome can provide unprecedented insight into the molecular and epigenetic mechanisms regulating an activity. For example, gene transcription could have various epiproteomes that regulate initiation, elongation and termination. A recently realized milestone for measuring local epiproteomes has been the development of affinity enrichment procedures to isolate small regions of chromatin (Byrum et al., 2013; Byrum et al., 2012b; Dejardin and Kingston, 2009; Akiyoshi et al., 2009; Hoshino and Fujii, 2009; Griesenbeck et al., 2003; Unnikrishnan et al., 2010; Hamperl et al., 2014). Purification of a small region of chromatin from the cellular milieu is one of the most challenging aspects of these approaches as the proteins and histone PTMs specifically isolated with the targeted chromatin typically constitute a small fraction of the identified proteins—most of which are non-specific associations (Byrum et al., 2013; Byrum et al., 2012b; Byrum et al., 2011a). We developed two approaches using quantitative high resolution mass spectrometry that distinguish whether proteins and histone PTMs identified during epiproteome measurements are “specific” to the target chromatin or are “non-specific” contaminants (Byrum et al., 2013; Byrum et al., 2012b). These quantitative approaches are critical components of our ChAP-MS (Chromatin Affinity Purification with Mass Spectrometry) platform of technologies that enable local epiproteome analysis. Included in this platform are the first generation ChAP-MS and second generation TAL-ChAP-MS approaches (Byrum et al., 2013; Byrum et al., 2012b). The ChAP-MS approach, which used a targeted LexA protein as an affinity reagent, demonstrated the first unambiguous epiproteome measurement. The TAL-ChAP-MS approach achieved similar high resolution and specificity by using the genomic targeting ability of the TALEN (Transcription Activator-Like Effector Nuclease) system for local epiproteome isolation and analysis (Byrum et al., 2012b; Scholze and Boch, 2011).

Described here is the third generation technology termed CRISPR-ChAP-MS (FIG. 9). The prokaryotic viral defense system CRISPR (Clustered Regularly Interspaced Palindromic Repeats) has recently been developed as a genome-editing tool for eukaryotes (Mali et al., 2013). The core components of this system include the Cas9 nuclease, which is able to create double-strand breaks in DNA, and guide RNA (gRNA), which is bound by Cas9 and serves to direct this complex to a target sequence complementary to the gRNA. Using the Type II CRISPR system from S. pyogenes, we have harnessed the specific gene-targeting capability of the Cas9/gRNA complex to isolate and unambiguously identify a specific local epiproteome. We created a PrA-tagged version of Cas9 with a catalytically inactive nuclease along with a gRNA to target the promoter region of the GAL1 gene in S. cerevisiae to validate the CRISPR-ChAP-MS technology (FIG. 9).

To isolate the targeted chromatin, cells were treated with formaldehyde to stabilize interactions (Byrum et al., 2012b), chromatin was sheared to fragments approximately 1 kb in length, and the target chromatin was affinity purified using the PrA tag. Affinity tagged versions of Cas9 have been shown to target chromatin for partial enrichment (Fujita and Fujii, 2013); however, a quantitative analysis of the specifically bound proteins and histone PTMs has not been reported. Here using our CRISPR-ChAP-MS approach that does provide for quantitative identification of specifically bound proteins and histone PTMs, the GAL1 promoter chromatin from yeast was isolated under transcriptionally active conditions and subjected to a label-free quantitative mass spectrometric workflow to identify the specific components of the local epiproteome. Relative to the first and second generations of the ChAP-MS technological platform, CRISPR-ChAP-MS shows an enhanced ability to isolate targeted chromatin, which is critical for epiproteome analysis. The TAL-based approach also requires design of a specific TAL protein for each sequence targeted whereas CRISPR-ChAP-MS only requires site-directed mutagenesis to alter the gRNA for genomic targeting, which provides a more cost effective approach that can easily be multiplexed to target additional sites.

Example 6. A CRISPR-Based Approach for High Resolution Epiproteome Identification

To validate the CRISPR-ChAP-MS approach, the promoter chromatin of the GAL1 gene was targeted for enrichment in S. cerevisiae. This region of chromatin is an attractive target for validation studies as one can supply yeast with galactose in place of glucose to rapidly and synchronously stimulate transcriptional activation of GAL1—thereby setting a transcriptionally active chromatin state for epiproteome analysis. Cells were transformed with plasmids expressing a nuclease inactive and PrA-tagged version of Cas9 (pPrA-Cas9) and/or expressing gRNA specific to the promoter region of the GAL1 gene (pgRNA-GAL1). Similar expression of PrA-Cas9 in glucose and galactose was demonstrated by Western-blotting (FIG. 10A). To evaluate whether expression of this PrA-Cas9/gRNA complex affected transcription of GAL1, cDNA was prepared from cells in glucose (transcriptionally repressed GAL1) and galactose (transcriptionally active GAL1) and was analyzed by quantitative real-time PCR. GAL1 transcription was similar in cells expressing PrA-Cas9/gRNA compared to cells expressing only PrA-Cas9, indicating that expression of PrA-Cas9/gRNA does not drastically alter transcriptional activation (FIG. 10B). To determine whether this expressed PrA-Cas9/gRNA complex was bound to and could enrich chromatin at the GAL1 promoter region, ChIP was performed to PrA-Cas9 in cells from glucose and galactose cultures. GAL1 promoter chromatin was enriched in a gRNA dependent manner with PrA-Cas9 from both glucose (4.9-fold) and galactose (70-fold) growth conditions (FIG. 10C). Regions 2 kb up- or downstream did not show enrichment (FIG. 10C), demonstrating that chromatin purification was localized to the gRNA target region. In previous studies using TAL proteins targeted to the same chromatin region (Byrum et al., 2013), a ˜6-fold enrichment was observed under galactose growth conditions and no enrichment under glucose growth. Therefore, the enrichment observed with PrA-Cas9/gRNA in galactose-containing media is greater than an order of magnitude higher relative to a TAL targeted to this region of chromatin.

To determine if enrichment using CRISPR-ChAP was specific, a series of potential off-target sites were analyzed (FIG. 10C). The four most similar sites in the genome to the first 12 base-pairs of the 20 base-pairs targeted at GAL1 by gRNA-GAL1 were analyzed by qPCR-ChIP for PrA-Cas9/gRNA binding. The first 12 base-pairs of the 20 base-pair target sequence strongly influence gRNA-directed binding specificity (Fu et al., 2013). The off-target (OT) sites contained 14/20 (OT1), 15/20 (OT2), 15/20 (OT3) and 13/20 (OT4) of sequence identity relative to the GAL1 target DNA. Two of the four off-target sites showed 3.2- and 4.4-fold (OT1 & OT2) enrichment with PrA-Cas9/gRNA (FIG. 10C). For most effective targeting of Cas9 to a genomic region, the 20 base-pair target region needs to contain a protospacer-activation motif (PAM motif) immediately 3′ to the target DNA. In the type II S. pyogenes system used in this work, the PAM motif is NGG (Mali et al., 2013; DiCarlo et al., 2013). Accordingly, OT1 and OT2 that showed Cas9/gRNA enrichment contained a PAM motif, while OT3 and OT4 did not. This demonstrated that off-target binding of the PrA-Cas9/gRNA complex targeting GAL1 is enhanced with a PAM motif and can provide ˜4-fold off-target enrichment. This ˜4-fold off-target enrichment is much lower than the 70-fold enrichment observed for transcriptionally active GAL1 promoter chromatin and will not complicate large scale proteomic approaches as the specifically bound proteins/PTMs will dominate the mass spectrometric data collection. The enrichment of GAL1 promoter chromatin under glucose growth conditions was 4.9-fold whereas off-target binding can contribute up to ˜4-fold enrichments. Therefore, purification of GAL1 promoter chromatin under glucose growth conditions was not pursued for large scale proteomic analysis, but rather the 70-fold enriched chromatin from galactose growth conditions was used for subsequent proteomic studies. The Cas9/gRNA and previously reported TAL results illustrate that DNA-binding affinity reagents may differentially access chromatin in different states; thus, care has to be taken to test for specific enrichment prior to proteomic studies (Byrum et al., 2013). As the CRISPR-based approaches become more engineered for DNA-binding specificity, off-target issues will have less impact on the CRISPR-ChAP-MS approach (Jiang et al., 2013).

To demonstrate the utility of the CRISPR-ChAP-MS approach, the GAL1 promoter chromatin was enriched from 1×10¹⁰ cells that were grown in media containing galactose. As a control for quantitative mass spectrometric identification of proteins as “specific” or “non-specific” to the purification, CRISPR-ChAP-MS was performed with PrA-Cas9 expressing cells either with or without gRNA-GAL1. Of particular importance for purification of small regions of chromatin, an experimentally-determined amount of formaldehyde cross-linking and sonication must be used to ensure that a native chromatin region can be isolated and analyzed (Byrum et al., 2013; Byrum et al., 2012b; Byrum et al., 2011a). Cells were cross-linked with 1.25% formaldehyde, lysed under cryogenic conditions with a ball mill, and after thawing were sonicated in purification buffer to yield chromatin fragments ˜1 kb in length. Dynabeads coated with IgG were used to affinity purify the PrA-Cas9/gRNA complex or control PrA-Cas9 with any associated proteins and posttranslationally modified histones. Isolated proteins were resolved by SDS-PAGE (FIG. 11A), excised from the entire gel lane in 2 mm bands and subjected to in-gel trypsin digestion. Tryptic peptides were analyzed by high resolution mass spectrometry with a Thermo Velos Orbitrap mass spectrometer as reported (Byrum et al., 2013). Proteins and histone PTMs (acetylation and mono-, di- and trimethylation of lysine) were identified with Mascot (Tables 9 & 10).

To determine which proteins were specifically enriched with the GAL1 promoter chromatin, a quantitative mass spectrometric approach was used to compare proteins identified with PrA-Cas9/gRNA and PrA-Cas9 alone. This reported approach uses normalized spectral abundance factors to represent the relative level of each protein in each sample, which can then be cross-compared to identify those proteins/PTMs enriched with PrA-Cas9/gRNA (Byrum et al., 2013; Zybailov et al., 2006; Byrum et al., 2013b). Using this approach, 86 out of 1832 identified proteins were found to enrich with PrA-Cas9/gRNA (Table 9). 11 of the 86 proteins were related to transcription (Rebl, Spt5, Toa2, Bafl, Sin3, H2B2, Ume1, Pob3, Rsc6, Rpa14, Rsc7), while the other 75 were common contaminants found in affinity enrichments (Byrum et al., 2013; Byrum et al. 2012b). In addition to proteins, acetylation of lysine 14 on histone H3 (H3K14) and H3K23 were found enriched with the GAL1 promoter chromatin (Table 10). Both H3K14ac and H3K23ac are correlated to active transcriptional states of chromatin. ChIP for a subset of these proteins/PTMs (Spt5, Pob3, Rsc6, Rsc7 and H3K14ac) was used to verify that these proteins/PTMs are components of the epiproteome at the targeted region of GAL1 promoter chromatin (FIG. 11B). H3K14ac was identified at the GAL1 promoter region with our first and second generation ChAP technologies (Byrum et al., 2013; Byrum et al. 2012b), while Pob3, Spt5, Rsc6 and Rsc7 are unique to this study. Pob3 forms a complex with Spt16 to make yFACT, which promotes chromatin rearrangement to allow progression of RNA polymerase. Spt16 was identified with our first and second generation ChAP technologies at GAL1 (Byrum et al., 2013; Byrum et al. 2012b); thus, providing compelling evidence that yFACT is localized to this chromatin region during transcriptional activation. Spt5 is an elongation factor that aids RNA polymerase II, while the RSC complex of proteins serves as a chromatin remodeler that is involved with transcription. Taken together our results present a snapshot of the dynamics of transcriptional activation within a 1 kb viewing window at the GAL1 promoter chromatin. This analysis demonstrates that the CRISPR-ChAP-MS approach can be used to identify a local epiproteome.

The CRISPR-ChAP-MS approach provides a new tool to study epigenetic regulation. Researchers can now identify proteins and histone PTMs at 1 kb resolution using proteomic approaches that do not depend on a priori knowledge of the protein/PTM target, which distinguishes this method from traditional ChIP. Key to success with chromatin enrichment procedures is the quantitative mass spectrometry used to determine which identified proteins/PTMs are “specific” to the isolated chromatin. These mass spectrometric approaches can be label-free, as used here and in our TAL-based second generation ChAP methodology (Byrum et al., 2013), or utilize an isotopically heavy label, as used in our LexA-based first generation methodology (Byrum et al. 2012b). Relative to the TAL-based and LexA-based ChAP methodology, our PrA-Cas9/gRNA approach showed greatly enhanced enrichment of targeted chromatin, which is instrumental for analyzing low copy cellular entities like specific chromatin sections. Furthermore, the Cas9/gRNA system is easily manipulated by simply altering the gRNA sequence, which provides for adaptability and multiplexing approaches. Recent and future efforts to further engineer the specificity of the Cas9/gRNA system will only expand the capabilities of the CRISPR-ChAP-MS approach (Jiang et al., 2013). This technology is immediately applicable to cell culture and in vivo systems that provide for expression of the Cas9/gRNA machinery. The CRISPR-ChAP-MS approach suggests far-reaching applicability for identifying molecular components driving chromosomal activities.

Methods for Example 6 Cloning, Western-Blotting, Real-Time Reverse Transcription PCR and Chromatin Immunoprecipitation (ChIP)

Cas9 was subcloned from Addgene plasmid 44246 (www.addgene.org/CRISPR/; Cross Lab) into pPrA-LexA (TRP1 selection) (Byrum et al. 2012b)—fusing Cas9 with a PrA (Protein A) tag to make pPrA-Cas9. Addgene plasmid 43803 (www.addgene.org/CRISPR/; Cross Lab) was used to express the gRNA (URA3 selection). The gRNA sequence in the plasmid was mutated in two steps using a Stratagene site-directed mutagenesis kit to produce the following sequence matching 20 base-pairs in the GAL1 promoter region:

(SEQ ID NO: 372) 5′ATTTGAAGGTTTGTGGGGCC. Three S. cerevisiae strains (W303 matA) were created by transforming the resulting plasmids: pgRNA-GAL1, pPrA-Cas9, and pPrA-Cas9+pgRNA-GAL1. Western-blotting, real-time reverse transcription PCR and chromatin immunoprecipation (ChIP) were as described (Byrum et al. 2013; Byrum et al., 2012b). Off-target sites used in FIG. 10C were:

(SEQ ID NO: 373) OT1 5′ATGAAAAAATTAGTGGGGCC, (SEQ ID NO: 374) OT2 5′ATACGTAGTCTTGTGGGGCC, (SEQ ID NO: 375) OT3 5′TACGGAAGGTTGGTGGGGCC, (SEQ ID NO: 376) OT4 5′TATGTCGCGTTTGTGGGGCC.

CRISPR-ChAP-MS.

S. cerevisiae with pPrA-Cas9 or pPrA-Cas9+gRNA-GAL1 were grown to mid-log phase in synthetic yeast media (minus tryptophan and minus tryptophan/uracil respectively) with 3% galactose and subjected to 1.25% formaldehyde cross-linking for 6 minutes. Cross-linking was quenched with 125 mM glycine for 5 minutes. Cells were collected by centrifugation and lysed under cryogenic conditions (Byrum et al., 2012b). Lysate from 10¹⁰ cells was re-suspended in purification buffer (25 mM HEPES-KOH, 0.5 mM EGTA, 1 mM EDTA, 10% glycerol, 0.02% NP-40, 150 mM KCl, 1× Sigma fungal protease inhibitor cocktail, 4 μg/mL Pepstatin A, 2 mM PMSF) at 5 mL/gram cell lysate. Re-suspended cell lysate was subjected to sonication with a Bioruptor to shear chromatin to ˜1 kb in size as described (Byrum et al. 2013; Byrum et al. 2012b). PrA-tagged Cas9/gRNA complex and associated proteins were affinity purified on 144 mg of IgG-coated Dynabeads (Byrum et al. 2013; Byrum et al. 2012b). IgG-coated beads were incubated with lysate for 7 hr at 4° C. with constant agitation. Beads were collected with magnets and washed twice in purification buffer, once with purification buffer with 1 M NaCl/1 M urea, and once in purification buffer. Proteins were eluted from the washed beads with 0.5 N ammonium hydroxide/0.5 mM EDTA for 5 minutes at room temperature. Eluted proteins were lyophilized, re-suspended in Laemmli loading buffer, resolved by 4-20% gradient SDS-PAGE, and visualized by colloidal Coomassie-staining. Gel lanes were sliced into 2 mm sections and subjected to in-gel trypsin digestion (Byrum et al. 2012b). Tryptic peptides were analyzed by high resolution tandem mass spectrometry with a Thermo Velos Orbitrap mass spectrometer coupled to a Waters nanoACQUITY LC system (Byrum et al. 2013; Byrum et al. 2012b). Proteins and histone PTMs (lysine acetylation and methylation) were identified with Mascot (Tables 9 & 10). To determine if a protein was “specific” or “non-specific” to the purification, a previously reported quantitative mass spectrometry approach was utilized (Byrum et al. 2013). In brief, a normalized spectral abundance factor (NSAF) value was calculated for each protein in the PrA-Cas9 and PrA-Cas9/gRNA purifications. The NSAF value is the number of spectral counts assigned to a given protein (normalized by the molecular weight of that protein) divided by the sum of all normalized spectral counts of all proteins identified in the specific purification (Zybailov et al., 2006). A fold-change of normalized NSAF values was then used to identify proteins specific to the PrA-Cas9/gRNA purification (Table 9).
